Nu2 counter test
From Bobs Projects
nu2_counter_test is a Verilog module to provide a never-ending source of 64-bit data compatible with the user_data_path module queues of the NetFPGA Reference Design framework.
It is normally used as a source of test data for testing the NetFPGA USB 2 v0.3 interface and it's associated NetFPGA USB 2 v0.3 firmware
It can be instantiated in nf2_core to inject packet data in the output queue leading to the USB interface, or it can be instantiated in nf2_usb2 to inject the test data directly into the nu2_tx_queue for testing.
