3.5.1.18. Report Time Borrowing Data

You can run the Timing Analyzer's Reports > Timing Slack > Report Timing... command to generate a report showing time borrowing data. The equivalent scripting command is report_timing (with specific arguments).

The Timing Analyzer reports time borrowing data for the Data Arrival Path or Data Required Path, according to whether borrowing occurs at the destination or the source.

Figure 76. Report for Time Borrowing At DestinationThe following report shows 100ps borrowed on the Data Required path. The setup slack improves on incoming paths, at the expense of worse setup slack for outgoing paths.
Figure 77. Report for Time Borrowing At SourceThe following report shows 100ps borrowed on the Data Arrival Path, worsening the setup relationship for the outgoing path.
