Displays the non-scan cells whose model type you specify.

The Report Nonscan Cells command displays the instance name, gate number,
and model type of the non-scan cells that you specify. The tool assigns a model
type to the non-scan cells during the Design Rules Check (DRC) in order to model
non-scan memory behavior more exactly.

During scan loading, scan clocks can affect non-scan memory elements. The
worst case is to assume that all non-scan memory elements will have an unknown
state right after scan loading, which makes some faults difficult to test. Therefore,
the tool assigns an appropriate model type to the non-scan cells, which sets them
to known values. The argument descriptions that follow describe the conditions
that the tool uses to make the various model type assignments.

•

-All

An optional switch that displays all non-scan cells. This is the default.

•

-INITX (FlexTest Only)

An optional switch that displays the non-scan cells which FlexTest initializes
to X after each loading.
