I often read that 10% IR drop may cause 7% performance degrade..
Does the 10% mentioned here represents VDD drop+VSS drop? If so, what is the deffernt between 2%VDD/8%VSS and 5%VDD/5%VSS?
I'm not sure about the impact of VSS drop to output high voltage(CMOS, voltage pull up by VDD, seems irrelevant with VSS ).
