Verilator has a new feature called "IMPLICTSTATIC warning", when a function is implictly static, in the version v5.006.
When I run the command make -f $RV_ROOT\tools\Makefile
The shell print
%Warning-IMPLICITSTATIC: /home/hiramhsu/W-VeeR/Cores-VeeR-EH1-main/testbench/dasm.svi:393:17: Function/task's lifetime implicitly set to static
And the building procession will be stopped because of these warnings.
I have to downgrade the version of verilator into v5.004 so that I can run the simulation.
