compare configure

The compare configure command modifies options for compare signals and regions. The modified options are applied to all items in the specified compare path.

Syntax

compare configure

[-clock <name>] [-recursive] [-tol <delay>] [-tolLead <delay>]
[
-tolTrail <delay>] [-when {<expression>}] <comparePath>

Arguments

-clock <name>

Changes the strobe signal for the comparison. Optional. If the comparison is currently asynchronous, it will be changed to clocked. This switch may not be used with the -tol,
-tolLead, and -tolTrail options.

-recursive

Specifies that signals should also be selected in all nested subregions, and subregions of those, etc. Optional.

-tol <delay>

Specifies the default maximum time the test signal edge is allowed to trail or lead the reference edge in an asynchronous comparison. Optional. The default is 0. If a unit is used (e.g., ps) with the time value, the time must be in curly braces.

-tolLead <delay>

Specifies the maximum time a test signal edge is allowed to lead a reference edge in an asynchronous comparison. Optional. The default is 0. If a unit (e.g., ps) is used with the time value, the time must be placed in curly braces.

-tolTrail <delay>

Specifies the maximum time a test signal edge is allowed to trail a reference edge in an asynchronous comparison. Optional. The default is 0. If a unit is used (e.g., ps) with the time value, the time must be placed in curly braces.

-when {<expression>}

Specifies a conditional expression that must evaluate to "true" or "1" for differences to be reported. Optional. The expression is evaluated at the start of an observed difference. See "GUI_expression_format" for legal expression syntax.

<comparePath>

Identifies the path of a compare signal, region, or glob expression. Required.
