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

# suppress spurious warnngs about 
# "Extra checking for conflicts with always_comb done at vopt time"
# because vsim will run vopt

# default to config/rv64ic, but allow this to be overridden at the command line.  For example:
# do wally-pipelined.do ../config/rv32ic
# That said, I don't think there are any peripherals that use anything but rv64i just yet.
