Error in Simple system VCS+Verdi simulation, Failed to find the Verdi database #2143
Comments
I modified the "ibex_simple_system.core" file and added a "-kdb" option, then the problem seems to be solved.

This looks like a sensible change to me. (And the VCS support in that file was written by me, back in 2020!) Are you happy to open a PR with it? |
Happy to that! I will open a pull request asap. |
Observed Behavior
I simulated the simple system example using VCS, following the guide in https://github.com/lowRISC/ibex/blob/master/examples/simple_system/README.md
I build the simulation with:
fusesoc --cores-root=. run --target=sim --tool=vcs --setup --build lowrisc:ibex:ibex_simple_system --RV32E=0 --RV32M=ibex_pkg::RV32MFast --SRAMInitFile=./examples/sw/simple_system/hello_test/hello_test.vmem
It showed success.
Then I run the simulator as:
/build/lowrisc_ibex_ibex_simple_system_0/sim-vcs/lowrisc_ibex_ibex_simple_system_0 -gui &
Then I came across the error:
If I don't use the DVE GUI,
./build/lowrisc_ibex_ibex_simple_system_0/sim-vcs/lowrisc_ibex_ibex_simple_system_0
It seems OK
So I would really appriciate it if you could help me solve this problem.
