What is standard cell library characterization?
Cell library characterization is a process of analyzing a circuit using static and dynamic methods to generate models suitable for chip implementation flows.
Why is cell library characterization needed?
No digital chip is possible without cell models. These cell models are produced by cell library characterization using commercial softwares like guna. Every digital chip implementation (rtl-to-gdsII) flow requires cell models for analysis (logic simulation, verification, timing, power, noise etc), implementation (synthesis, test insertion, placement, clock tree synthesis, routing) and fixing (engineering change order, rule fixing etc).
How is cell library characterization performed?
Cell library characterization typically takes cell design extracted as spice circuit and spice technology models. Characterization software like guna, analyzes this information to
