Hello everyone,
I don't clearly understand the difference between average / RMS / peak electromigration (EM) results of ANSYS Totem.
When I check power or signal EM I get the highest EM(%) in average EM mode, and the lowest EM comes in peak mode. It is strange for me.
For example at a differential amplifier tail the average signal EM is 80%, RMS signal EM is 30%, peak is 0%.
Or power EM of VDD33A rail is 40% in average, 30% in RMS, 20% in peak mode.
How Totem solves average, rms, peak? Does it use else integration time or bandwidth limit or something else? Is it normal that the peak EM is the lowest?
Thanks in advance.
