BrqRV EB1 RISC-V Core 1.0 from MERL

This repository contains the brqrv eb1 Core design RTL. Brqrv Eb1 Is A Machine-Mode (M-Mode) Only, 32-Bit Cpu Small Core Which Supports Risc-V’s Integer (I), Compressed Instruction (C), Multiplication And Division (M), And Instruction-Fetch Fence, And Csr Extensions. The Core Contains A 4-Stage, Scalar, In-Order Pipeline

Testing of Design

Go to verilog/dv/BrqRV_EB1/ directory

  1. Set the GCC_PATH environment variable.
  2. Set the PDK_PATH environment variable.
  3. Copy the given program hex file into uart.hex.
  4. run the make commad for RTL simulation
  5. run the SIM=GL make command for netlist simulation

Note: Dont forget to add 0x00000FFF instruction in the end of the uart.hex to stop the uart transmission if you are using your own codes.
