|
If you do not specify the Error, Warning, Note, or Ignore option, then the handling is either set to the previous handling or set to the Design Rules Checker default.
∙NOVerbose
An optional literal that specifies for the tool to display the occurrence message only once for the rules violation. This is the default.
∙Verbose
An optional literal that specifies for the tool to display the occurrence message for each occurrence of the rules violation.
∙NOAtpg_analysis
An optional literal that specifies for the tool not to use test generation analysis when performing rules checking. This is the default.
∙Atpg_analysis
An optional literal that specifies for the tool to use test generation analysis when performing rules checking for clock rules (such as, C1, C3, C4, C5 and C6), some D rules (such as D6 and D9), and some E rules (such as, E4, E5, E8, E10, E11, and E12).
For clock rules C3 and C4, the Atpg_analysis option generates a check of the clocks of the source and sink to see if they are gated off. To see if a path exists from the Q output of the source to the sink, use the Set Sensitization Checking command with checking turned on. It is recommended that you use the Atpg_analysis option with the Set Sensitization Check On analysis to remove the maximum number of false C3 and/or C4 violations.
If you want the tool to use the constraint values during the D6 rule analysis, you must use the Atpg_analysis option.
Note
∙
A switch, a literal (A), and a string triplet that specifies the name of the clock on which the tool performs further analysis to screen out false C3 and C4 clock rules violations.
