//// ////
//// This file is part of the YIFive cores project ////
//// https://github.com/dineshannayya/yifive_r0.git ////
//// http://www.opencores.org/cores/yifive/ ////
//// ////
//// Description ////
//// This is a standalone test bench to validate the ////
//// Digital core. ////
//// 1. User Risc core is booted using compiled code of ////
//// user_risc_boot.c ////
//// 2. User Risc core uses Serial Flash and SDRAM to boot ////
//// 3. After successful boot, Risc core will write signature ////
//// in to user register from 0x3000_0018 to 0x3000_002C ////
//// 4. Through the External Wishbone Interface we read back ////
//// and validate the user register to declared pass fail ////
//// ////
//// To Do: ////
//// nothing ////
