RISCV_Verilog

This code was finished mainly during my sophomore year within a week, which lacks a good coding style, especially in single. But the implementation of pipeline is carefully verified by a series of test codes provided by TA. There might still be some undetected bugs so feel free to come up with any issue.

You can run the code with machine code generated by programs in assembler.

The DEBUGGER module is used to debug the design with an explicit view of the Register, which should be commented out if you like to synthesize or upload the design to an FPGA.

Build

I build this project using iverilog and view the wave file with gtkwave. So below building guide will based on above tools.

To start, you have to run the assembler inside ./assembler, to get the machinecode.txt.

For single

1. Copy the machinecode.txt to ./single.
2. Change directory (cd) to ./single.
3. Run iverilog riscv_soc_tb.v -o riscv to compile.
4. Run vvp ./riscv to run the code. You'll notice some outputs and the wave file wave.vcd.
5. Use gtkwave wave.vcd to view the wave.

For pipeline

Pretty much the same as above.

1. Copy the machinecode.txt to ./pipeline.
2. Change directory (cd) to ./pipeline.
3. Run iverilog riscv_soc_tb.v -o riscv to compile.
4. Run vvp ./riscv to run the code. You'll notice some outputs and the wave file wave.vcd.
5. Use gtkwave wave.vcd to view the wave.
