Command Dictionary Mark

∙-All

A switch that marks all the gates in the design.

∙-Select

A switch that marks all the gates in the current selection list.

Examples

The following paragraphs provide examples of using various commands to display gates and their effect on the mark feature.

The first example displays three levels of fanout gates from the number one input of gate 51 and marks gate 51 in the display:

ADD DIsplay Instances 51 -I 1 -F -Level 3

In this case, the marking is additive such that marked instances stay marked and the key instances will be added to the marked list. However, if Set Schematic Display -Compact is active and was used to compact instance 51 during creation of a schematic, then DFTInsight will not mark the instance nor add it to the marked list, even if you later set the schematic display to -Nocompact.

The next example generates a textual display of a specific rule failure and then performs a DRC violation analysis:

report drc rules c4-12

//Warning: Clock /ain[0] failed rule C4 on input 3 of //bilbo_brreg_bstage[8]_nlatch2 (14736). (C4-12)

//Source of violation: input 3 of

//bilbo_brreg_bmuxstage[8]_nlatch2 (14790)

analyze drc violation c4-12 -display

The Analyze Drc Violation command marks within the display the following instances, which its sister command, Report Drc Rules, noted earlier: /ain[0], 14736, and 14790. This marking is not additive because the Analyze Drc Violation command replaces the previous schematic.
