Description
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.
Arguments
∙-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.
