* fpga: x400: Fix x4xx_qsfp_wrapper testbenchWade Fife2021-06-221-0/+3
| | | | | Reorder dependencies so that sc_util_v1_0_vl_rfs.sv gets compiled first when using ModelSim.

* 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.
* fpga: tools: Fix python2 reference in viv_ip_builder.makWade Fife2021-06-171-1/+1
|
* fpga: tools: Add modelsim.excludesWade Fife2021-06-171-0/+18
| | | | | 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: Add ip target to simulation makefilesWade Fife2021-06-172-2/+6
| | | | | Allow building of just the IP by running "make ip" in simulation directories.

* fpga: Update rfnoc_image_core for all targetsWade Fife2021-06-1018-5780/+6492
| | | | | | Update rfnoc_image_core.v to take into account the new image_core_name fields and version strings. Add new rfnoc_image_core.vh. Update YAML where needed.

* 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: Change RFNoC YAML version numbers to stringsWade Fife2021-06-0810-20/+20
| | | | | Change version from a numeric to a string, in order to differentiate between versions like "1.1" and "1.10".
* fpga: lib: Add modports to SV AXI-Stream blocksWade Fife2021-06-034-8/+8
|
* fpga: lib: Add time_increment port to timekeeperWade Fife2021-06-031-17/+43
| | | | | Adds a time_increment port for situations in which the parameter TIME_INCREMENT can't be used. They offer the same behavior.
* fpga: lib: Pipeline ctrlport_timerWade Fife2021-06-031-24/+81
| | | | | | | This pipelines ctrlport_timer to eliminate the long combinational path caused by the time comparisons. This change also removes the PRECISION_BITS parameter and converts it to a signal named time_ignore_bits.

* fpga: tools: Add ability to patch IP during generationWade Fife2021-06-032-0/+87
| | | | | | This adds the ability to call BUILD_VIVADO_IP, as before, followed by REBUILD_VIVADO_IP_WITH_PATCH to patch a file generated by the IP and then rebuild the IP with the patched file.
* fpga: tools: Add support for RFSoCHumberto Jimenez2021-06-032-9/+9
| | | | | | | This commit includes the following changes to the tools: - Change part definition in XCI and BD editors for the RFSoC family - Resolve part name in Vivado IP management utilities with viv_gen_part_id.py
* fpga: lib: Minor cleanup of axi_lite.vhLars Amsel2021-06-031-2/+23

* 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: Add rx_front_end_gen3 testbenchWade Fife2021-04-092-0/+247
|
* 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.
