cpan install Verilog::Pli

Otherwise, untar, make, test, and install manually: cd Verilog-Pli-* perl Makefile.PL make make test make install

Introduction to Verilog-Pli

Written by Wilson Snyder <wsnyder@wsnyder.org>.

Summary

Verilog::Pli provides the ability to call Verilog PLI functions from inside Perl.

$cmd ("print 'Inside perl, on ', `date`, \"\\n\";");
$display (" 1 + 2 = %x\n", $cmdval("1+2"));
$cmd ("$Sparse{", 230000, "}", "=", 32'hfeed);
$cmd ("$NET{w} = 0;");

And, the ability to access the value of Verilog nets from Perl.

print 'The value of wire x is ', $NET{x}, "\n";
