用PrimeRail做dynamic IR drop的分析时,报告中有这么一段话, Power domain VSS network voltage report
PEAK transient voltage:
Min voltage rise (mV) = 0
Max voltage rise (mV) = 2.405e3
Min voltage drop (mV) = 0
Max voltage drop (mV) = 799.54e-3
AVG transient voltage:
Min voltage rise (mV) = 0
Max voltage rise (mV) = 25.658
Power domain VDD network voltage report
PEAK transient voltage:
Min voltage rise (mV) = 0
Max voltage rise (mV) = 692.877e-3
Min voltage drop (mV) = 0
Max voltage drop (mV) = 2.315e3
AVG transient voltage:
Min voltage drop (mV) = 0
Max voltage drop (mV) = 32.553
需要关注的是PEAK transient voltage还是AVG transient voltage,这两个值哪个是我们所说的dynamic IR drop呢
