Error (SIGNATURE_DUMP_SFW) Failed to detect expected writes to signature region

[superbchetan]

Hi,
While executing the make clean simulate verify postverify XLEN=32 RISCV_DEVICE=Vi command I am encountering following error for work/rv32i_m/Vi/VADC-VIM-SEW16_LMUL1.*

Error (SIGNATURE_DUMP_SFW) Failed to detect expected writes to signature region

Any idea, why I am hitting this error?

Regards,

This error means that although configured with a region of memory to contain the signature no writes were ever detected into this signature region i.e. this means that the test did not run as expected.
I suggest enabling tracing of the reference model (contained in the riscvOVPsimPlus) to see what happened during execution.
Turn on tracing by adding the following to the execution command line
RISCV_TARGET_FLAGS="--trace --tracechange"
