Phoenix NoC- Verilog

This project is a implementation of the Phoenix NoC (originally designed in VHDL) using the Verilog HDL.

Configuration

The files here configure a 3x3 NOC, to receive packages with 9 flits of 16 bits each.

To change the size of the NoC: rtl/defines.vh change NUM_X and NUM_Y to the number of routers you want in each axis. Then in tb/noc.h change the defines num_router and num_y;

To change the size of the flits in a package, in rtl/defines.vh change TAM_BUFFER so one package can fit in the buffer.

It is also necessary to configure the number of test packages: In tb/noc.h change num_pkg

The files in tests were generated by a java traffic-gen and are adapted to the current configuration of the NOC, if you want to test another configuration you need to generate new input files.

Dependencies

verilator

Command line arguments

The main in /tb receive the files in /tests which are used as input packages to the router with matching address

Defines

__VERILATOR

This define must be used to adapt the top file NOC.v to the simulation via Verilator

Make commands

all

$make all

Compile necessary files using verilator to create an executable program.

tests

$make tests

Run all traffic input files in /tb
