Why do we set separate threshold point when determining the ECSM capacitance at pin level and timing level? The format for pin level is: Code: Pin A { ... ... ecsm capacitance (rise) { threshold_pct =50.0 index1=(...) values=(...) } ... ... } for timing arc level: // .... rise_transition() { waveform_1 {} waveform_'n' {} ecsm_capacitance (rise) { threshold_pct = 50.0 ... } ecsm_capacitance (rise) { threshold_pct = 70.0 ... } } What does threshold_pct mean and why we set seperate threshold points to sweep the capacitances? Thank you, Last edited by a moderator: Aug 16, 2017
