Using the Synopsys® Design Constraints Format Application Note

Beyond setup and hold timing, the tool must honor physical design rule constraints dictated by the semiconductor foundry. These take priority over performance optimization:

Once an accurate SDC profile is established, Design Compiler executes multi-level optimization routines to map the RTL design into target library cells (gates) while respecting constraints. Optimization Phases synopsys timing constraints and optimization user guide 2021

The 2021 guide splits ECO into two distinct phases: or Fusion Compiler.

set_output_delay specifies the time required by the external device outside the chip boundary before the next capturing clock edge.

The logic gates and interconnect wires that delay the signal.

To streamline your team's configuration process, I can provide automated SDC generation scripts or design templates. Please let me know: What or period you are shooting for?

A constraint is a rule you type into the software. It tells the tool exactly how fast the data must move.

Clocks are the heartbeat of any synchronous digital system. Improperly constrained clocks will invalidate your entire timing analysis. Ideal Clocks vs. Real Clocks
