Dear all SI gurus, How to compose a unloaded driver waveform at die from a given IBIS driver model? I think inside the IBIS model, the VT tables provides the information of driver waveforms with specific test loads, for example, 50 ohms pull up /pull down. However, when the driver drive a transmission line , ie, system load., the unloaded driver waveform shall be used instead of the test loaded driver waveform. Thank you for your helps in advance.
