//// APB- SPI 0.1 IP Core VIP ////
//// ////
//// This file is part of the APB- SPI 0.1 IP Core project ////
//// http://www.opencores.org/cores/APB- SPI 0.1 VIP for IP Core ////
//// ////
//// Description ////
//// Implementation of APB-SPI bridge IP core testing using ////
//// UVM based VIP core's TB_top document. This top level block ////
//// includes interfaces of APB slave and SPI master and will be ////
//// driven using UVM based agents ////
//// ////
//// To Do: ////
//// Addition of exact signals of the Top level DUT. ////
//// Due to different configurations that may be possible, the ////
//// interfaces and hence the UVM driver signals might vary ////
