- 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.
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.
Connect the DAC data underflow pin (fifo_rd_underflow) of the DMA
to the dunf pin of the device core. This way the software can detect
underflows in the DAC data path.
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.

Some IP core have files in their file list for common modules that are not
used by the IP itself. Remove those.

Removes a lot of boilerplate code.
Using the new scheme it is possible to add new projects or sub-projects
without having to re-generate any existing Makefiles.

This reduces the amount of boilerplate code that is present in these
Makefiles by a lot.
It also makes it possible to update the Makefile rules in future without
having to re-generate all the Makefiles.

Explicitly disable the "Transfer Start Synchronisation Support"
since the sync lines are not connected in this project.
If the sync input line (s_axi_user[0] or fifo_wr_sync) are not connected,
Vivado 2017.4.1 no longer connects them to the defaultValue defined
in the axi_dmac ip (1). Instead he uses the defaulValue field defined
in the interface definition which in case of both interfaces is 0;
The constraint where added to remove timing problems on the reset path.
The constraint paths do not match anymore. The resets are used in a synchronous
way so we don't need the timing exceptions anyway.

- daq3
- adrv9739
- ad6676evb
- fmcadc5
- daq2/kcu105

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.

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.

The DAQ3 does not use a 1-to-1 lane mapping for the DAC JESD204 link.
Provide the proper mapping when setting up the transceiver connections.
Without this the payload data will be mapped incorrectly and the
transmitted signals are scrambled.

Convert the DAQ3 project to the ADI JESD204 link layer cores. The change is
very straight forward, but a matching change on the software side is
required.

Move the CDC helper modules to a dedicated helper modules. This makes it

All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.
New license looks as follows:
