Wormhole packet-switching Network-on-Chip with XY routing.

Testing

Inside sim/ there is a script for simulating with modelsim:

vsim -c -do sim.do

The simulation parameters are present in sim/tb.sv. Change the parameters X_SIZE and X_SIZE to simulate.

To generate simulation traffic, run the script present in sim/inputs

./traffic-generator.py

It is possible to customize the traffic generator parameters in traffic-generator.py. Please check the parameters size, bandwidth, rate, amount, x_total, and y_total.
