The Prelayout Checker checks your design for possible error conditions before you place-and-route. Prelayout checks are a subset of the Design Rule Check (DRC). If the Prelayout Checker finds potential errors, it displays warning and error messages in MultiView Navigator's Log window.
To run the Prelayout Checker, from the Tools menu, choose DRC. Use the DRC command to check for errors before you use the Layout command.
Selecting DRC performs the following checks:
Validates common macros in overlapping regions against the overlap capacity
Checks placement of I/Os against the banks' voltage settings
When you choose Commit and Check from the File menu in the MultiView Navigator, it automatically performs comprehensive checking in addition to committing the changes to your design.
