Hi, I have case in which TX and RX are from different vendors. RX is Impulse_Init_Return only (No GetWave Function is available) and TX is GetWave only (No Init_impuse_Return is available). When I run this simulation, IR of passive channel and analog models of TX and RX is created. Let's call it IR1 (Let say IL of channel is 20dB, so IR1 is impulse response of 20dB IL) Let say TX is set to -6dB de-emphasis. IR1 is send to GetWave of TX model which outputs waveform which is 6dB de-emphasized. But IR1 is not affected due to Getwave function of TX. What I have seen in the simulation is this IR1 is also send to RX Init_Impuse_Return function and RX Equalizer works on 20dB channel rather than 20dB + (-6dB de-Emphasis) channel. And hence I always get over-equalized response in simulation. What is solution to this? Please help. Thanks, Darshan
