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_SRC 0 \
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.

In case the same device clock is used for multiple JESD204 links, e.g. a TX

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

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
sub-project and all, clean, clean-all targets in the form 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.

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.

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.
