LEXICON RISC-V Core 1.0 from MERL
This repository contains the Lexicon Core design RTL. Lexicon 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/Lexicon/ directory
Set the GCC_PATH environment variable. Set the PDK_PATH environment variable. Copy the given program hex file into uart.hex. run the make commad for RTL simulation run the SIM=GL make command for netlist simulation Note: Dont forget to add 00000FFF instruction in the end of the uart.hex to stop the uart transmission if you are using your own codes.
