Mentor v8.6_4 manual Set Ram Initialization, ∙ Uninitialized, ∙ Random

Command Dictionary Set Ram Initialization

Set Ram Initialization

Tools Supported: FastScan

Scope: Setup mode

Usage

SET RAm Initialization Uninitialized Random

Description

Specifies whether to initialize RAM and ROM gates that do not have initialization files.

The Set Ram Initialization command allows FastScan to internally generate random values and place them into all uninitialized RAM and ROM gates. This command is useful when simulating random patterns.

Arguments

∙Uninitialized

A literal that specifies for FastScan to use unknown (X) values to set the memory elements of all RAM and ROM gates which do not have an initialization file. This is the default behavior upon invocation of FastScan.

∙Random

A literal that specifies for FastScan to use random values to set the memory elements of all RAM and ROM gates which do not have an initialization file.

Examples

The following example places random values into all uninitialized RAM and ROM gates:

set ram initialization random set system mode atpg

set pattern source random add faults -all

run
