+//// 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 0x1003_0058 to 0x1003_006C ////
+//// 4. Through the External Wishbone Interface we read back ////
+//// from 0x3003_0058 to 0x3003_006C ////
+//// and validate the user register to declared pass fail ////
+//// ////
+//// To Do: ////
