//  MODULE      :   parameter_test
//
//  DESCRIPTION :   Test module to demonstrate parameter evaluation bug.
//
//  AUTHOR      :   Brendan J Simon (brendan.simon@bigpond.com)
//
//  DATE        :   Monday 5th January 2001.
//
//  NOTES       :   It seems that Icarus Verilog 0.4 does not evaluate
//                  moderately complex parameter statements properly.
//
