Static Transmission Gate Check (static_tgate)

Description

Reports the transmission gates which cause potential leakage currents between power supplies.

These gates can be characterized by their node connectivity, based on the following:

- nodes which connect to the gate and NMOS drain/source terminals, but not to the PMOS drain/source terminals

- nodes which connect to the gate and PMOS drain/source terminals, but not to the NMOS drain/source terminals

The results are written to the static.xml file, which can be viewed in a Web browser. This check is supported only by XPS and APS.

Syntax

Name static_tgate parameter=value ...

Parameters

Design check parameters

node

[...]

Nodes to which the check is applied. Default is none.

Filtering parameters

error_limit

10000

Maximum number of errors reported. Default is 10000.

Wildcard scoping

inst

[...]

Subcircuit instances to which the check is applied. Default includes all instances (inst=*).

xinst

[...]

Subcircuit instances to be excluded from the check. Default is none.

subckt

[...]

The instances of the specified subcircuit to which the check is applied. Default includes all subcircuits (subckt=*).

xsubckt

[...]

The instances of the specified subcircuits that are excluded from the check. Default is none.

depth

8

Hierarchy levels (starting from top, instance, or subcircuit scope) to be checked. Default is 8.
