For all the Xilinx base design, define three global clock nets, which
are saved in the following three global variable: $sys_cpu_clk, $sys_dma_clk
and $sys_iodelay_clk.
These clock nets are connected to different clock sources depending of
the FPGA architecture used on the carrier. In general the following
frequencies are used:
- sys_cpu_clk - 100MHz
- sys_dma_clk - 200MHz or 250Mhz
- sys_iodelay_clk - 200MHz or 500Mhz
Define a MIMO_ENABLE parameter for the core, which will insert
and additional de-skew logic to prevent timing issues coming from
the clock skew differences of two or multiple AD9361.
Add support for the Arria 10 SoC development kit to the dac_fmc_ebz
project.
This allows to use the following FMC boards on the Arria 10 SoC development
Kit carrier:
* AD9135-FMC-EBZ
* AD9136-FMC-EBZ
* AD9144-FMC-EBZ
* AD9152-FMC-EBZ
* AD9154-FMC-EBZ
* AD9171-FMC-EBZ
* AD9172-FMC-EBZ
* AD9173-FMC-EBZ
Note that the board in its default configuration is not fully compatible with the
mentioned FMC boards and some slight re-work moving some 0 Ohm resistors is
required. The rework concerns the LA01 and LA05 pins, which by default are
not connected to the FPGA. The changes required are:
LA01_P_CC
R612: R0 -> DNI
R610: DNI -> R0
LA01_N_CC
R613: R0 -> DNI
R611: DNI -> R0
LA05_P
R621: R0 -> DNI
R620: DNI -> R0
LA05_N
R633: R0 -> DNI
R632: DNI -> R0
The main differences between AD9144-FMC-EBZ and AD9172-FMC-EBZ are:
* The DAC txen signals are connected to different pins
* The polarity of the spi_en signal is active low instead of active high
* The maximum lane rate is up to 15.4 Gpbs
To accommodate this all 4 possible txen signals as well as the spi_en
signal are connected to GPIOs. Software can decide how to use them
depending on which FMC board is connected.
Note that each carrier has a maximum supported lane rate. Modes of the
AD9172 (and similar) that exceed the carrier specific limit can not be used
on that carrier. The limits are as following:
* A10SoC: 14.2 Gbps
Add a generic project for the AD91xx-FMC-EBZ DAC boards connected to the
ZCU102 and ZC706 carrier boards.
The project is called dac_fmc_ebz as the intention is to support all DAC
FMC evaluation boards with this project since they are sufficiently similar
to be supported by the same design.
This project will successively extended to add support for more boards.
The desired DAC device and JESD operation mode must be selected from the following
file:
./common/config.tcl
This design can support the following FMC boards which are all pin
compatible:
* AD9135-FMC-EBZ
* AD9136-FMC-EBZ
* AD9144-FMC-EBZ
* AD9152-FMC-EBZ
* AD9154-FMC-EBZ
* AD916x-FMC-EBZ
* AD9171-FMC-EBZ
* AD9172-FMC-EBZ
* AD9173-FMC-EBZ
Note that the AD9152-FMC-EBZ only uses the first 4 lanes, whereas all other
boards use 8 lanes.
This project assumes that the transceiver reference clock and SYSREF are
provided via the clock distribution chip that is found on the
ADxxxx-FMC-EBZ board.
In terms of pin connections between the FPGA and the FMC board the
AD9172-FMC-EBZ is very similar to the AD9144-FMC-EBZ.
The main differences are:
* The DAC txen signals are connected to different pins
* The polarity of the spi_en signal is active low instead of active high
* The maximum lane rate is up to 15.4 Gpbs
To accommodate this 5 txctrl signals as well as the spi_en signal are connected
to GPIOs. Software can decide how to use them depending on which FMC board
is connected.
Note that each carrier has a maximum supported lane rate. Modes of the
AD9172 (and similar) that exceed the carrier specific limit can not be used
on that carrier. The limits are as following:
* ZC706: 10.3125 Gbps
* ZCU102: 15.4 Gbps (max AD9172 lanerate)
* SPI and GPIOs to PMOD header support
Connect a SPI interface and some GPIOs to the PL PMOD headers on the zcu102
and zc706 carriers.
This is can be used to control additional external hardware like a clock
chip or an analog front-end.
This is especially useful on FMC boards that do not feature a clock
generator chip.
The pin out is:
PMOD 1: SPI clock
PMOD 2: SPI chipselect
PMOD 3: SPI MOSI
PMOD 4: SPI MISO
PMOD 7: GPIO 0
PMOD 8: GPIO 1
PMOD 9: GPIO 2
PMOD 10: GPIO 3
The GPIOs are mapped at offset 48-51 of the EMIO GPIOs.
Add a clock crossing bridge for the interfaces that runs on a different
clock than the emif_user_clk.
This way we can simplify the main interconnect, and prevent occasional
timing violations.
The process ad_xcvrcon has a device_clk attribute which can be used to
connect a custom device clock to the XCVR. Fix the proc call so we can
simplify the block design script.

After the previous commit that removed the interconnects from HP ports

assigned to a specific range and address.
Allow the top level files to have parameters.
Pass the parameters from system_project.tcl to the Vivado/Quartus project and
to the block design scripts through ad_project_params variable.
Usage:
1. create a project with a list of parameters:
adi_project_xilinx my_project [list PARAM_A PARAM_A_VALUE PARAM_B PARAM_B_VALUE]
or
adi_project_altera my_project [list PARAM_A PARAM_A_VALUE PARAM_B PARAM_B_VALUE]
2. access the parameter in QSYS or block design through the $ad_project_params variable
e.g
set PARAM_A $ad_project_params(PARAM_A)
set PARAM_B $ad_project_params(PARAM_B)
3. In system_top.v use PARAM_A and PARAM_B as parameters/generics
Look for undefined clocks which do not show up in the timing summary
therefore can lead to silent failures.
If clocks are not defined they are not analyzed during the timing
checks.
This commit add support for the dual AD9208-DUAL-EBZ board.
The clocking scheme is different from the other projects.
The device clock (LaneRate/40) is no longer an output of the transceivers (RXOUTCLOCK),
it is received directly from the clockchip SCLKOUT9 output through the REFCLK1.
This is needed for deterministic latency where SYSREF must be sampled
with the device clock by meeting setup and hold time.
The two channels from each converter are merged together and transferred to the DDR with a single DMA.
It has all transceiver parameters set for a 15Gpbs lane rate and uses the QPLL.
REQUIRED HARDWARE CHANGES : The F1 2A fuse must be populated on the FMC
board.
Clear the reference checkpoint if the incremental compilation is not
selected through the make option. Other case the scripts will silently
use the reference.dcp checkpoint if that exists.
The scripts are looking for a previous run result, a routed design
checkpoint to use it as a reference during the incremental build flow.
Before clearing the project files, the scrips will save the reference dcp
file in the project folder.
If the reference dcp does not exists the build continues normally.
Proposed workflow:
1. Build your project normally with 'make' or place manually a
reference.dcp file in the Vivado project folder.
2. Do some minor modifications
3. Run the make with the following option:
make MODE=incr
4. Repeat steps 2-3
Using a common IP cache location for all the project will speed up
compile time of common blocks used in base designs. Example a MicroBlaze
core for VCU118 once compiled it will be reused on other projects.
Using a common IP cache will speed up re-compiles of every project in OOC
mode since the cache won't be cleared as with normal compile flow.
Having a clock assigned manually to the clk output pin of the axi_ad9361
let the Vivado timing engine to not ignore the clock insertion delay when
analyzing paths between clk_0 and the manually created clock that has
the same source (clk_0), resulting in timing failure.
In the current form, when connecting a master to the HP ports all
available slave address spaces are mapped to the master (DDR_*, PCIE*, OCM,
QSPI)
Let the PL masters have access only to the DDR_LOW and DDR_HIGH address
spaces to avoid unnecessary resource usage and increase timing margin.
Create the dacfifo/adcfifo infrastructure with procedures.
This will allow moving the parameters of the dac/adcfifo inside
the block design so it can be calculated based on other parameters.

When we improve timing by modifying the implementation strategies,
the general rule of thumb is "less is always more".
Timing did not fail in synthesis, so we leaving the synthesis
strategy in default.
After several parallel runs with various strategies, the
"Performance_Explore" strategy gave the best result for
implementation.
Each individual link of a multi-link has its own sync signal. The top level
sync port that is created by the ad_xcvrcon function is always a single bit
single though.
This results in only the sync signal of the first link being routed while
others are ignored.
To fix this make sure that for multi-link setups the sync port is a vector
port with the width equal to the number of links.

- refclk and refclk_rst were used for ethernet IDELAY, but are not needed anymore
- muxaddr_out pins overlap with regular GPIOs in the Zed base design. The XADC mux GPIOs can be controlled through that. Cusomters that want to directly control the pins through XADC IP must modify the design
In default strategy we having a few path with small negative slack inside of
the MIG, due to the high UI clock (300MHz).
This new strategy solves this issue.
Add support for specifying a set of parameter value pairs when
instantiating an IP core to the ad_ip_instance command. This has the
convenience of not having to repeatedly call ad_ip_parameter with the name
of the core that got just created for each parameter that needs to be set.
It is also useful for cases where some parameters have mutually exclusive
values and both (or more) have to be set at the same time.
This also slightly speeds things up. Whenever a parameter is changed the
core needs to be updated and post configuration scripts might run. When
setting all parameters at the same time this only happens once instead of
once for each parameter.
For example the following sequence
ad_ip_instance axi_dmac axi_ad9136_dma
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_TYPE_SRC 0
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_TYPE_DEST 1
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_DATA_WIDTH_SRC 64
ad_ip_parameter axi_ad9136_dma CONFIG.DMA_DATA_WIDTH_DEST 256
can now be replaced with
ad_ip_instance axi_dmac axi_ad9136_dma [list \

DMA_TYPE_DEST 1 \
DMA_DATA_WIDTH_SRC 64 \

The loopback on the unused gpio inputs consumes routing resources
while does not gives any value for the software.
Connect these lines to zero instead.
Some projects use the ad_iobuf on IOs that are not bidirectional
producing synthesis warnings.
The change fixes warnings like:
[Synth 8-6104] Input port 'gpio_bd_i' has an internal driver
[Synth 8-6104] Input port 'gpio_status' has an internal driver
- connect unused GPIO inputs to loopback
- connect unconnected inputs to zero
- complete interface for system_wrapper instantiated in all system_top
fixes incomplet portlist WARNING [Synth 8-350]
fixes undriven inputs WARNING [Synth 8-3295]
The change excludes the generated system.v and Xilinx files.
- remove interrupts from system_top
- for all suported carriers:
- remove all interrupt bd pins
- connect to GND all initial unconnected interrupt pins
- update ad_cpu_interrupt procedure to disconnect a interrupt from GND
before connectiong it to another pin.
Just one VCC or GND xlconstant will be generated for each width. This
way we can avoid having a lot of xlconstant instances with the same
configuration.
Some FMC boards do utilize more than one transceiver quad but do not
necessarily use all transceivers in a quad. On such board is the
AD9694-500EBZ. Which uses two transceivers each in two adjacent quads.
This board can not be supported by instantiating a util_adxcvr with only 4
lanes. Since those 4 lanes would be packed into the same quad. Instead it
it is necessary to instantiate a util_adxcvr with 6 lanes. 4 lanes for the
first quad and 2 for the second.
To still to be able to connect such a util_adxcvr to a link layer with only
4 lanes allow to specify sparse lane mappings. A sparse mapping can have
less lanes than the util_adxcvr and some lanes will be left unconnected.
For example for the AD9694-500EBZ the lane mapping looks like the following:
ad_xcvrcon util_ad9694_xcvr axi_ad9694_xcvr ad9694_jesd {0 1 4 5} rx_device_clk

Sometimes the output clock of the transceiver should not be used for the
device clock.
E.g. for deterministic latency with no uncertainty the device clock needs
to be sourced directly from a clock or transceiver reference clock input
pin.
Add an option to the ad_xcvrcon command to specify the device clock.
In case the same device clock is used for multiple JESD204 links, e.g. a TX
and a RX link only one reset generator is created.

This change adds the TLAST signal to the AXI streaming interface
of the source side for Intel targets.
Xilinx based designs already have this since the tlast is part of the
interface definition.
In order to make the signal optional and let the tool connect a
default value to the it, the USE_TLAST_SRC/DEST parameter is
added to the configuration UI. This conditions the tlast port on
the interface of the DMAC.
Xilinx handles the optional signals much better so the parameter
is not required there.
There are random timing violations on the A10GX board using the
DAQ3 and DAQ2 projects.
Setting the synthesis/implementation strategy to "HIGH PERFORMANCE
EFFORT" increases the success rate of the timing closure significantly.
In the system top of the FMCOMMS5 projects, there are several GPIO lines, which
can not find in the constraint file, respectively gpio_open_15_15,
gpio_open_44_44 and gpio_45_45.
These are floating GPIO pins, as their names suggest. Delete all these wires and
update IOBUF instances.
Moved XCVR related connections to HP0, where the HP shares the MUX with the Video DMA
HP1 and HP2 are used for RX OS and RX DMAs, sharing the MUX. Usually they shouldn't run at the same time.

All HPx and DMA buswidths have been increased to 128 bits
The HPx-DMA clock has been increased to 300 MHz

Currently the individual IP core dependencies are tracked inside the
library Makefile for Xilinx IPs and the project Makefiles only reference
the IP cores.
For Altera on the other hand the individual dependencies are tracked inside
the project Makefile. This leads to a lot of duplicated lists and also
means that the project Makefiles need to be regenerated when one of the IP
cores changes their files.
Change the Altera projects to a similar scheme than the Xilinx projects.
The projects themselves only reference the library as a whole as their
dependency while the library Makefile references the individual source
dependencies.
Since on Altera there is no target that has to be generated create a dummy
target called ".timestamp_altera" who's only purpose is to have a timestamp
that is greater or equal to the timestamp of all of the IP core files. This
means the project Makefile can have a dependency on this file and make sure
that the project will be rebuild if any of the files in the library
changes.
This patch contains quite a bit of churn, but hopefully it reduces the
amount of churn in the future when modifying Altera IP cores.

Currently the IP component dependency in the Makefile system is the Vivado
project file. The project file is only a intermediary product in producing
the IP component definition file.
If building the component definition file fails or the process is aborted
half way through it is possible that the Vivado project file for the IP
component exists, but the IP component definition file does not.
In this case there will be no attempt to build the IP component definition
file when building a project that has a dependency on the IP component.
Building the project will fail in this case.
To avoid this update the Makefile rules so that the IP component definition
file is used as the dependency. In this case the IP component will be
re-build if the component definition file does not exist, even if the
project file exists.

This is implemented by creating virtual targets for each combination of

"$project/all", ... These virtual sub-targets are then listed as the
prerequisites of the project top-level Makefile targets.

The TX side runs on QPLL, and the RX and RX_OS runs on CPLL by default.
The OUTCLK frequency is the same as the REFCLK.
The main reason of this modification is that the links should come up
without any DPR access, after power up, using the default reference clock
configuration (122.88 MHz).
This way the user do not need to modify the block design, just
set the required rate in system_bd.tcl.

The constraint where added to remove timing problems on the reset path.

By default every base design has a SPI interface (hard or soft). In
case of soft IPs (xilinx), the input registers of the interface by default have
the IOB attribute set to TRUE. If the interface are not used, the tool will
generate a critical warning, stating that IOB registers are not connected to
an IO buffer.
The following constraints are disabling the above setup for every base
design, which using a soft SPI IP.
Set the properties to mirror the hardware configuration so
the Vivado tools can provide warnings if there are any conflicts
between configuration pin settings, such as an IOSTANDARD
on a multi-function configuration pin that conflicts with the
configuration voltage.

The following base constraints were updated:
- kcu105
- kc705
- vc707
- ac701
To reduce compilation time use default stratagies for synthesis and
implementation. If a project will require custom strategies, enable it
just for that particular project.
This modification will affect both Intel and Xilinx projects.
Vivado sometimes generates semi-valid or invalid warnings and critical warnings.
In the past these messages were silenced, by changing its message severity.
These setups were scattered in multiple scripts. This commit is an attempt
to centralize it and make it more maintainable and easier to review it.
The script specifies the OUT_CLK_SEL and SYS_CLK_SEL parameter values as
binary numbers. But the tools will interpret them as decimal number
resulting in the wrong selection for OUT_CLK_SEL. Specify the parameter
values as decimal values to avoid this.
This is not a critical issue since software will overwrite this setting at
system boot-up. But it should be fixed anyway.

Make sure that the axi_adxcvr instances are configured with the same
transceiver type as the util_adxcvr.
This is necessary for software to be able to detect the transceiver type
and support dynamic reconfiguration.
It is also necessary for correct eye scan support in the axi_adxcvr block.

Fix the location assignment of the transceiver blocks to get the correct
lane mapping.
Note that the comments indicating the expected lane mapping are correct,
but the actual transceiver location assignments were not.

The external reference clock runs at 122.88 MHz by default. This means that
the QPLL feedback divider needs to be set to 80 so that the VCO is inside
the locking range (9.8 GHz - 16.375 GHz).

DAC data underflow from the DMA, was not connected to anything. This
signal should be connected to the util_rfifo, which will forward it to
the device core.
+ Build both the read and write logic around an FSM
+ Consistent naming of registers and wires
+ Add support for burst lenghts higher than one, current burst lenght
is 64
+ Fix all the bugs, and make it work (first bring up with
adrv9371x/a10soc)
If the ADI_HDL_DIR or ADI_PHDL_DIR are set on Windows platforms, an
invalid TCL character (e.g. backslash) may be used as a file separator,
causing issues with the build / library scripts.
Normalize the paths before using them as global TCL variables.
Add support for the AD-FMCDAQ2-EBZ on the Arria10 SoC development board platform.
In its default configuration the Arria10 SoC development board is not fully
compatible with the AD-FMCDAQ2-EBZ and a slight rework is necessary,
changing the position of four 0 Ohm resistors:
R610: DNI -> R0
R611: DNI -> R0
R612: R0 -> DNI
R613: R0 -> DNI
R620: DNI -> R0
R632: DNI -> R0
R621: R0 -> DNI
R633: R0 -> DNI

Rework the peripheral address to match the updated semantics of
ad_cpu_interconnect, which expects that the addresses are in the range of
0x00010000 - 0x001fffff. This includes updating the base addresses as well
as compressing the used address range to fit into the 2Mb window.

The DDR memory reference clock on the A10SoC development board is
differential. Currently the EMIF core it is configured for single-ended
configuration, which causes it to generate incorrect IOSTANDARD
constraints. Those incorrect constraints get overwritten again in
system_assign.tcl, so things are working, but this generates a warning when
building the design
Configure the EMIF core correctly and remove the manual constraint overwrite since
they are no longer necessary.

There is no guarantee that the external reset de-assertion is synchronous
to the sys_clk, yet the clock bridge marks the reset de-assertion as
synchronized to the clock. This can cause recovery or removal timing
violations for the registers affected by this reset signal and potentially
bring the system into an invalid state after the reset is de-asserted.
Mark the reset as not synchronized to the clock signal, this will make sure
that Qsys inserts the proper reset synchronizers where required.

Currently the TX lane mapping is implemented by having to connect tx_phy_s_* to
the tx_ip_s_* and the tx_phy_d_* to the tx_ip_d_* signals in the system
qsys file in the desired order.
Re-work things so that instead the lane mapping is provided through the
TX_LANE_MAP parameter. The parameter specifies in which order logical lanes
are mapped onto the physical lanes.
The appropriate connections are than made inside the core according to this
parameter rather than having to manually connect the signals externally.
In order to generate a 1-to-1 mapping the TX_LANE_MAP parameter can be left
empty.
This change slightly reduces the boiler-plate code that is necessary to
setup the transceiver.

+ Add a HDL parameter for the PPS receiver module :
PPS_RECEIVER_ENABLE. By default the module is disabled.
+ Add the CMOS_OR_LVDS_N and PPS_RECEIVER_ENABLE into the CONFIG
register
+ Define a pps_status read only register, which will be asserted, if the free
running counter reach a certain fixed threshold. (2^28) The register can
be deasserted by an incomming PPS only.
Some of the standard Quartus components (especially the Merlin cores) generate
quite a few synthesis warnings. Lets assume these are false positives and
disable the warnings.

The PLL frequency must be half of the lane rate and the core clock rate
must be lane rate divided by 40. There is no other option, otherwise things
wont work.
Instead of having to manually specify PLL and core clock frequency derive
them in the transceiver script. This reduces the risk of accidental
misconfiguration.

While things seem to work fine with only specifying the the IO standard for
the positive side of differential signals Quartus will issue a warning
about incomplete constraints if the IO standard is not specified for the
the neagtive side as well. To avoid these warnings add the missing
constraints.

Both the sys_hps.f2sdram_clock and the sys_dma_clk.clk signal are in the
same clock domain. They are both driven by the same clock. And even though
qsys is capable of detecting this it seems qsys interconnect is not able to
infer this and inserts a extra clock domain crossing bridge between the DMA
and the HPS AXI system memory interface.
To avoid this connect the sys_dma_clk.clk to the sys_hps.f2sdram_clock so
that all components are driven by the same qsys clock signal.

Qsys allows to query to query the clock domain that is associated with a
clock input of a peripheral. This allows to automatically detect whether
the different clocks of the DMAC are asynchronous and CDC logic needs to be
inserted or not.
Auto-detection has the advantages that the configuration parameters don't
need to be set manually and the optional configuration will be choose
automatically. There is also less chance of error of leaving the settings
in a wrong configuration when e.g. the clock domains change.
In case the auto-detection should ever fail configuration options that
provide a manual overwrite are added as well.
