Hello, I was very pleased to find "Hardware-Verilog-Parser" which gave me a good start to parsing the Verilog file I have for further analysis. After doing a few setup steps I run: ( I am using Perl 5.8.8 x64 on Redhat Enterprise 4.0) perl ./parser.pl ./test1.v Gives output: gbr02488@acs0014.gb-sou01$ perl ./parser.pl ./test1.v parsing filename ./test1.v parsing filename ./test1.v Use of uninitialized value in array dereference at PrecompiledParser.pm line 56041, <FILE> line 38.

Jason, This is a true bug, but I have no idea why the author didn't encounter and fix it at the first time. As the author claimed, this module is in beta development stage, so we just take this easy. Before the author add a patch to v0.13, you may fix the above issue as follows: 1. Open 'generate_precompiled_parser.pl' file on root of the installation package for edit, replay '$item{range}' with '$item{q{range (?)}}' throughout the file. 2. execute 'generate_precompiled_parser.pl' and generate the 'PrecompiledPaser.pm', and the above problem would disappear! Further more, since the generated PrecompiledParser.pm is not copy to the installed directory automatically. You'd better to copy it to any location in your @INC manually. Hope this helps!
