Command Dictionary Set Ram Test

Set Ram Test

Tools Supported: FastScan

Scope: Atpg, Fault, and Good modes

Usage

SET RAm Test Static_pass_thru Read_only Pass_thru

Description

Specifies the mode for RAM testing with random or Built-In Self Test (BIST) patterns.

The Set Ram Test command specifies how FastScan tests RAM using random or BIST patterns. The default upon invocation of FastScan is Static_pass_thru. However, if during the design rules check FastScan encounters a violation that prevents you from using one of the RAM test modes, it displays a message telling you so and resets the RAM test mode accordingly. You can use the Report Environment command to display the current RAM test mode.

The Set Ram Test command does not affect the ATPG; it always considers all usable modes when creating a test pattern for a fault.

Arguments

∙Static_pass_thru

A literal that specifies to test RAMs in static-pass-through mode during random patterns. This is the default behavior upon invocation of FastScan.

∙Read_only

A literal that specifies to test RAMS in read-only mode during random patterns.

∙Pass_thru

A literal that specifies to test RAMs in dynamic-pass-through mode during random patterns.
