Dynamic Glitch Check (dyn

A 'Glitch' occurs when:

- A low signal goes above the mid-level, and crosses the mid-level again within the user-defined duration.

- A high signal goes below the mid-level, and crosses the mid-level again within the user-defined duration.

This check applies only to blocks with single and constant power supply.

The results are written to the dynamic.xml file, which can be viewed in a Web browser.

Design check parameters


`node`	`[...]`	Nodes to which the check is applied. Default is none.
`duration`	`5.00E-09 sec`	Duration threshold. Default is 5.00E-09 sec.
`min_duration`	`0 sec`	Minimum glitch duration threshold. Default is 0 sec.
`max_duration`	`5.00E-09 sec`	Maximum glitch duration threshold. Default is 5.00E-09 sec.
`low`	`0 volt`	Low-level voltage. Default is 0 V.
`high`	`(volt)`	High-level voltage. Default is none.
`mid`	`0.5*(high + low) volt`	Mid-level voltage for glitch detection. Default is 0.5*(high + low).

Filtering parameters


`time_window`	`[tstart, tstop] sec`	The time window during which the circuit check is applied. Multiple non-overlapping time windows are supported. Default time window is 0 to tend.
`error_limit`	`10000`	Maximum number of errors reported. Default is 10000.
`fanout`	`all`	Fanout setting to filter node with specified connection. This option is supported only in XPS.Possible values are all, gate and bulk.

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.
