Viterbi HDL Code Generator

This is a code generator for some kinds of viterbi decoders. It can generate the synthesiable verilog HDL codes. These have been verified under simulation. The generator itself is released under GPL license but the Verilog HDL codes generated by it is without any restrictions except you MUST keep the license note in each Verilog HDL codes. I will be glad to head these Verilog HDL codes be used in some applications. If you have any advices, please email to . And I have creat a project at sourceforge.net, too. You can find them here. http://viterbi-gen.sourceforge.net Now you can post questions http://groups.yahoo.com/group/vhcg (Disabled)
