Set Iddq Checks

Tools Supported: FastScan and FlexTest

Scope: All modes

Usage

SET IDdq Checks [-NONe -ALl {-Bus -WEakbus -Int_float -EXt_float -Pull -Clock -WRite -REad -WIre -WEAKHigh -WEAKLow -VOLTGain -VOLTLoss}...] [-WArning -ERror] [-NOAtpg -ATpg]

Description

Specifies the restrictions and conditions that you want the tool to use when creating or selecting patterns for detecting IDDQ faults.

The Set Iddq Checks command specifies the restrictions that the tool places on the patterns that it creates or selects for detecting IDDQ faults. These restrictions only apply during the actual time of the IDDQ measurement; the tool ignores them at other times during a pattern.

If you are using FastScan, violations of these restrictions do not directly cause the tool to reject a pattern.

If you are using FlexTest, it does not allow an IDDQ measurement when a violation of these restrictions occurs.

During simulation, whenever violations of the restrictions occur, the tool displays a message identifying the gate associated with the violation and the number of patterns in which the violations occurred. The handling of the violation can be either warning or error.

If you select -Error, simulation terminates at the first occurrence of a violation. You can use the Report Gates command to inspect the simulation values of all gates for patterns that violate the restrictions by first using the Set Gate Report command with the Error_pattern option.

Arguments

-NONe

An optional switch that specifies not to perform any checks. This is the default.
