Chapter 4Test Pattern File Formats

This chapter describes the test pattern file formats for FastScan and FlexText.

Each tool uses a slightly different format so this chapter is divided into the

following two major sections:

•“FastScan Test Pattern File Format” on page 4-1

•“FlexTest Test Pattern File Format” on page 4-12

The ASCII file describing the scan test patterns is divided into five sections,

which are named header_data, setup_data, functional_chain_test, scan _test, and

scan_cell. Each section (except the header_data section) begins with a

section_name statement and ends with an end statement. Also in this file, any line

starting with a double slash (//) is a comment line. The format of the data

contained in each section is described as follows.

The header_data section contains the general information, or comments,

associated with the test patterns. This is an optional section that requires a double

slash (//) at the beginning of each line in this section. The data printed may be in

the following format:

// model_build_version - the version of the model build program that was

used to create the scan model.

// design_name - the design name of the circuit to be tested.
