Comparescan User Guide

Application Examples

Special Syntax Examples

The examples in this section demonstrate Comparescan rule syntax. For more detail, see Chapter 6, “Writing Comparescan Rules.”

Commenting

Use a pound character (#) or two forward slashes (//) at the beginning of a comment.

# Comment to the end of the line. // Comment to the end of the line.

datafile1 golden.trn # Comment to the end of the line. datafile2 test.trn // Comment to the end of the line.

Continuing Long Lines

Use a backslash character (\) at the end of a line to continue that line on the next line.

compare top.module1.module2.module25.signalA \

top.module1.module4.module25.signalZ \

-neg 10 -pos 20

Note: The backslash must be the last character on a continued line.

Specifying Both a Golden and a Test File

The file that is specified as datafile1 is treated as the golden file, and the file that is specified as datafile2 is treated as the secondary file.

datafile1 file1.trn

datafile2 file2.trn

Specifying Filenames Using UNIX Filename Syntax

You can specify filenames in a rules file, on the comparescan command line, or on the

Compare Options form. The ../.. and ~ path specifiers are supported, as shown in the following examples:
