This section describes the options that are available for the DRC command line.
The -e option produces a report containing details about errors only. No details are given about warnings.
-o outfile_name
The -o option overrides the default output report file file_name.tdr with outfile_name.tdr.
The -s option produces a summary report only. The report indicates the number of errors and warnings found but does not supply any details about them.
The -v option reports all warnings and errors. This is the default option for DRC.
The -z option reports incomplete programming as errors. Certain DRC violations are considered errors when the DRC runs as part of the BitGen command but are considered warnings at all other times the DRC runs. These violations usually indicate the design is incompletely programmed (for example, a logic cell has been only partially programmed or a signal has no driver). The violations would create errors if you tried to program the device, so they are reported as errors when BitGen creates a BIT file for device programming. If you run DRC from the command line without the -z option, these violations are reported as warnings only. With the -z option, these violations are reported as errors.
