[SI-LIST] Re: Hspice with IBIS model containing driver schedule

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.

HSpice call for [DRIVER_SCHEDULE] IBIS Buffer:

b_Drv_io  Drv_nd_pu  Drv_nd_pd 
   +         Drv_out    Drv_in 
   +         Drv_nd_en  Drv_V_out_of_in
   +         Drv_nd_pc  Drv_nd_gc
+ file     = './drv_sched.ibs'
+ model    = 'drv_sched_model1'
+ buffer   = 6    $ Top Level Model I/O_open_drain buffer
+ typ      = typ
