Bug Description

Hi all,

if I run make verilate, it fails with multiple of undefined reference to 'Verilated::s_ns errors and one undefined reference to 'Verilated::commandArgs(int, char const**)'. Can you advice, how to proceed?

I did a better results with the latest Verilator version 4.200+ (I have debian11), but I needed to add

#include "Variane_testharness___024root.h" in ariane_tb.cpp and change there sram preload to memif.read(0x80000000, mem_size, (void*)(top->rootp->ariane_testharness__DOT__i_sram__DOT__gen_cut__BRA__0__KET____DOT__gen_mem__DOT__i_tc_sram_wrapper__DOT__i_tc_sram__DOT__sram.m_storage));

I can then run ISA tests, but there is no debug output....

If verilate the model with DEBUG=1, then I got Segmentation Fault error....
