SDCx

SDCx is SDC (Synopsys Design Constraints) toolkit. It provides a cli tool to handle SDC files and a SDC parsing library of Rust.

About SDC

SDC (Synopsys Design Constraints) is a de facto standard format to describe constraints for ASIC/FPGA design. The specification of SDC is published through Technology Access Program (TAP-in). SDCx supports SDC1.1 ~ SDC2.1 defined at the specification.

CLI tool

sdcx is a CLI frontend of SDCx. This provides the following features.

  • Check : Validate an input SDC file.
  • Format: Format an input SDC file.

Check

sdcx check validates an input SDC file. By default, sdcx uses SDC version according to set sdc_version command. If version is not specified, SDC 2.1 will be assumed. If --force-version option is provided, the version can be overrided.

$ cat test.sdc
set sdc_version 2.1
set_sense -positive pin; # set_sense is supported on SDC2.1 only
$ sdcx check test.sdc
$ sdcx check --force-version 2.0 test.sdc
error[sdcx::sdc::SdcError]: Unsupported command at SDC 2.0
