Hi John, I've added the [DRIVER_SCHEDULE] call for IBIS models within the Hspice netlist. Please make sure, that the so-called Top Level Model is of the same buffer type as the so-called scheduled buffers. You can see this in the short example of an IBIS file added below. I hope that this helps. Regards, Dirk.
