|******************************************************************************* | [IBIS Ver] 3.1 [File Name] drivesch.ibs [File Rev] 0.1 [Source] [Date] 7/16/98 [Comment char] |_char | | | The following model demonstrates the use of IBIS multistage driver | schedules to describe an inverting and non-inverting model | with pulsed turn-off of the pullup transistor in an output | stage. In this example, during pullup cycles the pullup driver | is turned on at time=0 and then turned off at time=10ns. The pulldown | driver is always on during the pulldown part of the cycle. | |******************************************************************************* | [Component] Driver-Schedule
