# Takes 1:10 to run RV64IC tests using gui

# Usage: do wally-batch.do <config> <testcases> <testbench> [-coverage] [+acc] [any number of +value] [any number of -G VAR=VAL]
# Example: do wally-batch.do rv64gc arch64i testbench

# Use this wally-batch.do file to run this example.
# Either bring up ModelSim and type the following at the "ModelSim>" prompt:
#     do wally-batch.do
# or, to run from a shell, type the following at the shell prompt:
#     vsim -do wally-batch.do -c
# (omit the "-c" to see the GUI while running from the shell)
