* fpga: rfnoc: Fix EOB loss in DUCWade Fife2021-08-087-218/+1858
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were some rare corner cases where the EOB could get lost in the DUC due to the dds_timed logic not always passing it through as it should. This resulted in an underflow error message at the end of transmission. This commit also fixes an issue where part of the last packet used a frequency shift of 0 instead of the requested frequency shift, and an issue where the first few samples of a burst used the wrong frequency shift value. Part of the fix includes adding a TUSER port to dds_sin_cos_lut_only. The TUSER port is built into the IP but was disabled. It is now enabled and set to 1 bit wide. This has a very small effect on resource usage and can be left unconnected when not needed. The dds_freq_tune block was shared by the DUC and DDC. To avoid affecting the DDC, a new version, dds_freq_tune_duc, is being added for the DUC to use that has the necessary fixes. The new dds_wrapper.v is a wrapper for the dds_sin_cos_lut_only IP. This IP has the undesirable behavior that new inputs must be provided to push previous outputs through the IP. This wrapper hides that complexity by adding some logic to ensure all data gets pushed through automatically. This logic uses the TUSER port on the IP. Finally, a testbench for dds_timed was added.
* fpga: sim: Add PkgComplex, PkgMath, and PkgRandomWade Fife2021-08-085-0/+546
| | | | | | | | | | | | PkgComplex adds functions for doing complex arithmetic in SystemVerilog simulation. PkgMath provides mathematical operations and constants that aren't built into SystemVerilog, such as a constant for pi and the function round(). PkgRandom adds randomization functions beyond what standard Verilog supports but that don't require any special licenses or simulators.

| | | | | | White Rabbit is not supported in X410, however the register map included an incorrect reference to this unsupported feature. This commit removes the WR reference from both the source and html files.

* fpga: tools: Detect assertions in ModelSim simulationWade Fife2021-06-171-2/+22
| | | | | | | This change allows assertion errors/failures in ModelSim to be detected and causes ModelSim to return a non-zero value when such an assertion error occurs. This allows the return value of ModelSim to be used to determine whether or not the testbench passed.
* fpga: tools: Put SIM_SRCS at end of compile orderWade Fife2021-06-171-1/+1
| | | | | | VHDL depends on the compile order. This commit changes the order so that SIM_SRCS are compiled last with ModelSim to avoid issues with dependencies.
* fpga: tools: Support new FPGA types in viv_simulator.makWade Fife2021-06-171-2/+2
| | | | | | This updates the existing PART_NAME generation used in simulation makefiles to work with newer part families by calling viv_gen_part_id.py to generate the part name needed by Vivado.

| | | | | This is a list of testbenches that don't work with ModelSim and should be excluded when running run_testbenches.py.
* fpga: tools: Add modelsim.ini to ModelSim callsWade Fife2021-06-174-7/+38
| | | | | | | | | | | This adds the MSIM_VIV_COMPLIBDIR environment variable to specify a non-default location for the compilation libraries. This also allows a modelsim.ini other than the one in the ModelSim installation folder to be used. By default, the one in the simulation libraries compilation directory will be used. This can be changed by setting MSIM_MODELSIM_INI to the one you want to use, or set it to an empty string to use the one in the ModelSim installation folder.
* fpga: tools: Add features to run_testbenches.pyWade Fife2021-06-171-6/+19
| | | | | | | | | | | | | | | | Run "make ip" in a separate step for each testbench. This allows some testbenches to work better with ModelSim because it needs IP files that aren't known until after the IP is generated. Make run_testbenches.py more log friendly. Add a -l/--logged option for when the output is being logged. In this case, we don't want to display elapsed time every second. Add "Begin TB Log:" and "End TB Log:" to the output to more easily tell where the output from one testbench ends and another begins. Use the basedir argument as the base directory in which to search for testbenches so that a subset of the repo can be easily specified.

* fpga: tools: Fix part selection in setupenvSam O'Brien2021-06-101-4/+12
| | | | | | | | | | | | | | The script setupenv_base.sh, which is used to setup the development environmnet in the open source toolchain, adds some functions to the shell that are used to interact with vivado. Some of the functions were looking in the wrong argument for the product name. This commit fixes the bug. In addition, supplying an incorrect part name returned a rather opaque error message. This commit also fixes the error handling so that the intended error message is displayed. Signed-off-by: Sam O'Brien <sam.obrien@ni.com>

* fpga: rfnoc: Add ability to disable output flow controlWade Fife2021-04-142-7/+22
| | | | | | | | | | | | | Per the RFNoC specification, if we set the frequency of flow control updates to 0 then the input stream will not send flow control status updates to the output stream handler. This change makes it so that when the frequency of flow control status updates is configured to be zero in the FPGA output stream handler (i.e., cfg_fc_freq_bytes and cfg_fc_freq_pkts are both 0 in chdr_stream_output) then the output stream handler will not use flow control. That is, chdr_stream_output will not expect stream status updates and will not restrict output packets.

* fpga: lib: Update round_sd to eliminate X from simulationWade Fife2021-04-091-14/+45
| | | | | | | | | | | | The asynchronous feedback loop on the err signal causes X to get stuck on the sum signal when simulating. This change adds a check for simulation only to force X to 0 so that unknown inputs get resolved once the inputs are known. Also added default values to the ports out and strobe_out, since having them uninitialized and without reset was causing simulation issues in other modules. The FPGA will initialize them to 0, so this change makes the code equivalent to real hardware behavior.
* fpga: lib: Fix simulation of axi_fir_filterWade Fife2021-04-091-1/+1
| | | | | | The always(*) block was never executing in some simulators because there were no signals on the right-hand side in the block. Changing it to an initial block ensures it always runs.
* TwinRX: Remove frontend filtermichael-west2021-04-081-59/+8
| | | | | | | | | | Removing the FIR filter in the frontend to reclaim resources and remove redundancy when using a DDC block. The default image has a DDC block, so only users making custom RFNoC images and using TwinRX will need to take care to properly downconvert the full bandwidth coming from the radio block.
