Some problem in View Waveform #107

Closed TruNcat3 closed 2 years ago

TruNcat3 commented 2 years ago

I want to know the wave in hardware simulation in shared-vadd. So I use the code in https://tapa.readthedocs.io/en/release/tutorial/fast_cosim.html?highlight=vivado#view-waveform

./vadd -xosim_save_waveform -xosim_start_gui -xosim_work_dir "./cosim" -bitstream ./vadd.xilinx_u280_xdma_201920_3.hw_emu.xclbin 1000

But this code just work once! Here is the log in console.

In other apps, the code also could not work for generating the wave.

Hello @TruNcat3, the -xosim_save_waveform and -xosim_start_gui option only works for our customized simulation, where you provide the ".xo" file instead of the "_hw_emu.xclbin" file. If you provide the "_hw_emu.xclbin" file, Vitis simulation will be invoked, and you need to add a Vitis configuration file to save the waveform.

Thank you @Licheng-Guo ! It works!
