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.
