corev-dv rand test issue

[vinomutty]

Hi
Please find below commands used for running test cases

command lines:
Available test programs
export CV_SW_MARCH=rv32imc
export CV_SW_PREFIX=riscv32-unknown-elf-
export CV_SW_TOOLCHAIN=/opt/lowrisc/lowrisc-toolchain-rv32imcb-20240206-1
export RISCV=/opt/lowrisc/lowrisc-toolchain-rv32imcb-20240206-1

For custom testcase :make test TEST= riscv_arithmetic_basic_test_0 CV_SIMULATOR=vsim USE_ISS=IMPERAS OVPSIM

COREV-DV Generated Tests:
make SIMULATOR=vsim corev-dv
make gen_corev-dv test TEST=corev_rand_arithmetic_base_test SIMULATOR=vsim USE_ISS=IMPERAS OVP

Thanks

Hi @vinomutty, this Issue seems to be the same one as #2537. If that is the case, please close that Issue and we will continue the discussion here.

A couple of comments:

• I need to see all of your commands, starting from git clone ... I am specifically looking to see which branch of the repo you have cloned and which directory you run the make commands from.
• The variable USE_ISS should be set to either "YES" or "NO" ("1" or "0" should also work). The CV32E40P environment does not support IMPERAS OVPSIM.
• As indicated in my comment in corev-dv rand test issue #2537, the problem seems to be with compiling the BSP:

Make is saying make[2]: Nothing to be done for 'all'. which means it is not compiling the BSP which means that the cv-verif library is not greated for the subsequent compile of the test-program:

collect2: error: ld returned 1 exit status

The error message cannot find -lcv-verif is the problem.

You can try a few things:

1. Make sure you are using the cv32e40p/dev branch of the core-v-verif repo. This is very important.
2. In the cv32e40p/sim/uvmt directory run make clean_all SIMULATOR=vsim and re-run the test.
3. Try the CORE-V prebuilt toolchain mentoned in the README (see my comment in corev-dv rand test issue #2537).
