hello , everyone:
do you use to simulate the pwb of mobile phone
In addition to functional
validation,it is necessary to perform rf circuit simulation to satisfy
the need of EMC.

EMC effects in PWB
level are usually simulated by EM (Electromagnetic) software as: HFSS,
Momentum etc. With this kind of software you can observe radiation patterns
etc from vias and see the effects of unterminated signals.
this kind of simulation is only good to obseve major obstacles and see
areas that are prone to problems. The real results would be obtained
only after the PWB is manufactured and populated with components. Only
then, you can see the real problems and tackle them accordingly.
