I have a question regarding simulating IBIS model using Spectre. IBIS model generation always has the die capacitance included and in the generated IBIS file you will have this value as “C_comp” value. Does the Spectre accounts for this capacitance from the IBIS file while computing the time domain voltage waveform during simulation ? If I add additional capacitance outside in the testbench, to model the die capacitance, then it will be double counting.
Does anyone know if Spectre is already accounting this C_comp during the time domain voltage wave computation from IBIS file, during simulation ?
