SoCCanvasFifthDemo – Constraint Generation (SDC)
Constraint는 스크립트가 아니라 설계 의도입니다.
🧭 How to design SoC with SoC Canvas
Episode 5에서는
Clock 구조로부터 SDC를 생성하는 과정을 보여드립니다.
Clock Diagram을 그대로 렌더링하여 SDC 선언을 추가할 수 있습니다.
✔️ create_clock, create_generated_clock
✔️ Clock Group
✔️ Exception
설계와 SDC가 분리되지 않으며,
설계 변경 사항은 SDC에도 실시간으로 반영됩니다.

SoCCanvasFifthDemo – Constraint Generation (SDC)
Constraints are design intents, not scripts.
🧭 How to design SoC with SoC Canvas
In Episode 5,
we show how to generate SDC directly from your Clock structure.
By rendering the Clock Diagram as-is, you can layer in SDC declarations right on top.
✔️ create_clock, create_generated_clock
✔️ Clock Group
✔️ Exception
The design and the SDC are not separated,
and design changes are reflected in the SDC in real time.

💡 Summary
In this video, we explore the SDC (Synopsys Design Constraint) feature of SoC Canvas, designed to simplify the generation of complex timing constraints once the clock design is complete.
SoC Canvas automatically converts the CMU (Clock Management Unit) structure into an SDC-oriented view, enabling engineers to generate Tcl-based constraints such as:
– create_clock
– create_generated_clock
By selecting declaration points directly from the diagram.
This “One Data” approach keeps RTL, timing, and physical design information synchronized in real time.
