Error when run in verilator: no viable conversion from 'const VlWide<92>' to 'const uint32_t [92]'

Hi!

When I run sudo make -f Makefile.verilator.mk, it reports errors:

I don't know why these errors occur. My environment configurations are as follows:

export RSD_ROOT=~/rsd
export RSD_GCC_PATH=/opt/riscv32/bin
export PATH=$PATH:$RSD_GCC_PATH
export RSD_GCC_PREFIX=riscv32-unknown-elf-
export RSD_VERILATOR_BIN=~/verilator/bin

It requires version v4.026 of verilator exactly. Otherwise, it may report errors.

I'm sorry for my late response. We have recognized the issue you explained and are working to support the latest Verilator. However, our current implementation has caused a significant slowdown in the latest version, and resolving it will require more time. Thank you for your report.
