By internalizing the principles of this guide—especially the proper use of multi-cycle paths, clock groups, and retiming—design teams can reduce their timing closure iterations by 40% or more. As the industry moves toward even more complex heterogeneous designs, the foundational lessons of the 2021 TCO guide remain as relevant as ever. Design Rule Constraints (DRC) Maximum Fanout : Setting
