Re: [Iverilog-devel] Looking for a $fatal opinion

[Stephen W. <st...@ic...>]

The $fatal() task prints a standard message, and allows the user to
include other data. The standard does say that the simulator should
return an error, and with this patch I have in mind, it would wind up
replacing $finish_and_return(1) for you. I just want to make sure
nobody gets caught off guard in a bad way if I apply this patch.
