It is a parser designed to parse HUGE files, a little bit at a time. Basically, it nibbles at a file while it parses. Grammars are written in pure perl using subroutines defined in the Parse::Nibbler package. installation instructions are: gunzip (tarball).tar.gz tar -xf (tarball).tar cd Parse cd Nibbler perl Makefile.PL make make test make install After you've done the install, you can cd into the t/ subdirectory and take a look at the test examples. The main documentation is POD at the end of the Parse::Nibbler.pm file itself. Contained in the t/ subdirectory is a grammar for parsing gate level verilog netlists, VerilogGrammar.pm. The test t/big_verilog.t runs a benchmarking test which times how long it takes to parse a large piece of verilog gate level code. 6000 lines of verilog in test file. On a P3 @ 750 MHZ, it currently parses gate level verilog at about *** 1420 *** lines per second. Current state of package: Alpha Any of the interfaces to the package may change at the next version. I've swapped from object oriented to subroutine calls, so nothing is sacred at this point. Hope things will settle down at some point though... trying to get the speediest approach possible, then I'll iron out the details.
