# Using -voptargs=+acc makes everything visible in the simulator for GUI mode
# and avoids some cases where simulation mismatch could otherwise occur.
# Setting -onfinish to "stop" prevents the simulator from immediately trying to
# exit when finish() is called. This is annoying in the GUI and important for
# error detection in batch mode.

# detection of error/failure assertions so that non-zero values are returned by
# ModelSim when the testbench doesn't pass. Calling std.env.finish() or
# $finish() will return 0. Detecting $fatal() requires that -onfinish be set to
# stop so the simulator doesn't quit before the DO file finishes.
