9、enter.IntroductionThe objective of the delay and power calculation system (DPCS) is to make it possible for integrated circuitdesigners to consistently calculate chip delay and power across electronic design automation (EDA)applications and for integrated circuit vendors to express delay and power i
10、nformation only once pertechnology while enabling sufficient EDA application accuracy.This is accomplished by a coordinated set of standards that support a standard method to describe timingand power characteristics of integrated circuit design units (cells and higher level design elements); astanda
11、rd method for EDA applications to calculate chip design instance specific delay, slew, and power forlogic and interconnects; and standard file formats to exchange chip parasitic and cluster information.Notice to usersLaws and regulationsUsers of these documents should consult all applicable laws and
