VCS simulator cannot generate the FSDB file

[Qijun Zhang]

Hi,

I have tried to generate FSDB file when simulating, so I firstly made a VCS simulator:

make debug CONFIG=SmallBoomConfig  

Then I used this to run the spmv in riscv-tests:

./simv-chipyard-SmallBoomConfig-debug ../../toolchains/riscv-tools/riscv-tests/benchmarks/spmv.riscv

But after that, there is no FSDB file in the directory, so I was wondering if there is something wrong in these two instructions above, and how could I generate a FSDB file using VCS simulator.

Thank you very much!

Best regards,

Qijun Zhang

Hello! I'm facing the same question, Have you fixed it?

Using the run-binary-debug make target will supply the right flags to the simulator binary to generate a fsdb waveform.

Thanks for your reply, I generated fsdb waveform successfully in this way!
