Hi IBIS experts (once again), Now about C_comp: in IBIS specification is written that the C_comp defines the silicon die capacitance and that influences [Ramp] parameters. Question would be how (is it used as capacitive load)? Is the [Ramp] the only parameter that is influenced by C_comp influences, or there are some other things too? I mean, when I generate [Rising Waveform] and [Falling Waveform] intrinsic capacitances of drivers and receivers, ESD structures and wiring are already accounted (in netlist), so I assume that taking into the account C_comp too would be kind of double counting. Later, when simulation tool is using IBIS model, if there are [Rising Waveform] and [Falling Waveform] this waveforms will be taken, so the information about driver/receiver, ESD and wiring capacitances will be "extracted" out of this curves, C_comp is not used - true or not? If there are no [Rising Waveform] or [Falling Waveform] the [Ramp] parameter will be taken (true or not?). In this case simulation tool is using only [Ramp] data (this data intrinsically contain C_comp), so the C_comp is not used (true or not?) Once again, many thanks for any help!
