There is still a fix here... I updated HEAD to warn if the $fopen etc descriptor isn't 64 bits so these errors can be... Wilson Snyder

09:14 pm Issue #22 (WillNotFix): no STMTDLY warning for always #1 -- blocks

#1 isn't one simulation time step, it's one time unit, they're different things. You're making an assumption about t... Wilson Snyder

09:06 pm Issue #22: no STMTDLY warning for always #1 -- blocks

In this case (always-statement delay for one simulation time step) the warning makes no sense. in all other situation... Holger Wächtler

There are some implementation issues, but the main issue is I consider Verilator a synthesis subset simulator, and ha... Wilson Snyder

mmh,... why verilator_file_descriptor, why should this be verilator-specific? Using `verilator_file_descriptor yields... Holger Wächtler

06:03 pm Issue #21 (AskedReporter): $fopen() & friends don't work as expected...

Works for me. Perhaps try
`verilator_file_descriptor infile, outfile;
instead of a integer.

I had assumed $stime is really a backward compatibility thing that code shouldn't be using any more.
