SI & PI analysis on the entire board level..

Hi,

I know some commercial tools, a possible simulator for SI&PI.( SIWAVE,MWS....)

I want to know SI&PI Simulation about realistic, accuracy, speed on the entire board level with discrete component (R,L,C..).

I don't understand you question that good. you want to know how accurate is a tool/simulation? or you want to know how to use/perform a too/simulation?
