Regarding Simulation of 'make run-example-c-project-verilator' in GitLab for CVA-5
Respected sir I trust this email finds you well. My name is Tanishq.S, and I am a student from PES University, India. I am reaching out along with my team as we are currently engaged in a Capstone project focusing on the analysis of the CVA-5 Processor Performance . After installing the toolchain and running the make file "make run-example-c-project-verilator" i got this 9errors and 5 warnings :
{Please see the Error obtained in the Screenshots attached to this ISSUE}

Interesting; I have never seen those errors. Which version of Verilator are you using? If it is an older one, you can try compiling a newer version of Verilator from source. I can confirm that Verilator 5.018 works.
