I use hspice E (VCVS or ICVS ...) make a ideal DAC
ADC ... but hspice not support "behavior command"
have anyone ever use saber ?? becuase I hope this behavior model can link with hspice .. someone told me saber can support it .
another choise is dolphin_smash .. it support spice & some language ..
but I don't know .. because we usually use matlab for behavior modeling , but matlab can not link with spice ..
