VCD and VPD File Utilities

VCD and VPD File Utilities 1

VCS comes with a number of utilities for processing VCD and VPD

files. You can use these utilities to perform tasks like creating

alternative VCD files, comparing the simulation data in two VCD,

EVCD, or VPD files, easily viewing the data in a VCD file, and

generating a VCD, EVCD, or VPD file that contains a selected subset

of value changes found in a given input VCD, EVCD, or VPD file.

Note:

All the utilities are available in $VCS_HOME/bin.

This chapter describes these utilities in the following sections:

• The vcdpost Utility

• The vcdiff Utility

• The vcat Utility

• The vcsplit Utility
