Transfer Filtering
By default, CDC Viewer reports include all transfer types:
- Timed transfers—passing or failing
- Fully cut transfers— transfers where all paths are false paths.
- Clock groups
- Inactive clocks
You can use these options to specify the type of transfers that display, or add transfer types as options: –timed, –fully_cut, –clock_groups, and –inactive. If you specify none of these, all transfer types display.

Keyword: report_cdc_viewer Settings: -timed|-fully_cut|-clock_groups|-inactive |
By default, only clocks that launch or latch paths that other clocks launch or latch appear. Turning on Non-crossing transfers shows clocks with transfers to or from themselves.
Scripting Information |
Keyword: report_cdc_viewer Settings: -show_non_crossing |
If you specify a value in the Maximum slack limit box, only paths with slack less than the value display. If you do not include this option, the report includes paths of any slack value.

Keyword: report_cdc_viewer Settings: -less_than_slack |
Grid Options
In grid format reports, you can configure the grid to display clocks as either a flat list or in a hierarchy in which generated clocks display as children of the clock from which they derive. Turn on Fold clocks on hierarchy to enable this nested display.
Scripting Information |
Keyword: report_cdc_viewer Settings: -hierarchy |
By default, clocks that launch or latch to no paths do not appear in grid format reports. You can display these clocks by turning on the Show empty transfers option.
