// Verilog Test fixture created by
// HDL Bencher 6.1i
// Thu Nov 13 13:48:38 2003
// 
// Notes:
// 1) This test fixture has been automatically generated from
//   your Test Bench Waveform
// 2) To use this as a user modifiable test fixture do the following:
//   - Save it as a file with a .tf extension (i.e. File->Save As...)
//   - Add it to your project as a testbench source (i.e. Project->Add Source...)
