Hello experts,
I'm trying to evaluate the impact of power plane noise on the HS signals. The
sim setup would require to apply a noise source on the PDN (somewhere btw power
plane and ground plane), also a PRBS source at the initial end of the t-line.
To my knowledge it looks only Cadence Sigrity Speed2000 can run such SI/PI
combined sim since the feedback I got from Keysight and ANSYS both said that
neither ADS nor SIWave can handle such sim case where time domain sim needs to
be run w/ the noise coupled from power/ground plane. Note the coupling needs to
be from the whole plane rather than injected at one point for the latter we can
simply use a sparam model of the PDN as the means of noise injection but this
would not be the equivalent of the plane coupling, right?
Any suggestion will be appreciated.
