Add Pin Equivalences

Tools Supported: FastScan and FlexTest

Scope: Setup mode

Usage

For FastScan

ADD PIn Equivalences reference_pin {equivalent_pin... {-Invert

inverted_pin...}}...

For FlexTest

ADD PIn Equivalences target_pin... [-Invert] reference_pin

Description

Adds restrictions to primary inputs such that they have equal or inverted values.

The Add Pin Equivalences command performs slightly differently depending on whether you use FastScan or FlexTest. The following paragraphs describe how the command operates for each tool.

FastScan Specifics

For FastScan the Add Pin Equivalences command specifies that all primary input pins named subsequent to the reference_pin take on the value (or the inverted value) of the reference_pin. You can specify both pin equivalences and inversions in one command line by listing all equivalent_pins before the -Invert switch and all inverted_pins after the -Invert switch.

Constrained pins may not be equivalent pins.

FlexTest Specifics

For FlexTest the Add Pin Equivalences command specifies that all primary input pins named prior to the reference_pin take on the value (or the inverted value) of the reference_pin. You can only specify either pin equivalences or inversions in one command line. If you need to specify both pin equivalences and inversions, you need to enter the command twice.
