WebMay 31, 2024 · SDC is a short form of “Synopsys Design Constraint”. SDC is a common format for constraining the design which is supported by almost all Synthesis, PnR and other tools. Generally, timing, power and area constraints of design are provided through the SDC file and this file has extension .sdc. WebThe Timing Analyzer makes it easy to use Synopsys® Design Constraint (SDC) commands to constrain complex clock structures, such as multiplexed clocks. The following shows …

WebMay 1, 2013 · The Set Clock Groups (set_clock_groups) constraint allows you to specify which clocks in the design are unrelated. The set_clock_groups command allows you to cut timing between unrelated clocks in different groups. The Timing Analyzer performs the same analysis regardless of whether you specify -exclusive or -asynchronous groups. Webset_clock_groups Description This is an SDC command which disables timing analysis between the specified clock groups. No paths are reported between the clock groups in both directions. Paths between clocks in the same group continue to be reported.
