// This file contains the paramenters which define the part for the
// Smart 3 Advanced Boot Block memory model (adv_bb.v).  The '2.7V Vcc Timing'
// parameters are representative of the 28F160B3-120 operating at 2.7-3.6V Vcc.
// These parameters need to be changed if the 28F160B3-150 operating at
// 2.7-3.6V Vcc is to be modeled.  The parameters were taken from the Smart 3 
// Advanced Boot Block Flash Memory Family datasheet (Order Number 290580).

// This file must be loaded before the main model, as it contains
// definitions required by the model.
