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.
