Abstract

In a circuit having a plurality of Off Chip Drivers (OCDs), a method for determining the noise voltage, in a period of time during which some OCDs switch and others do not switch, on the output of non-switching OCDs, such OCDs each providing, on an output signal line, a signal having a nominal di/dt for a given input di/dt, and having a characteristic variation in output di/dt with respect to input bias voltage (Slope), comprising the steps of:
