The target board is a Digilent Atlys FPGA board (Spartan-6 @ 100MHz), and the circuit was tested at different SPI clock frequencies.

The circuit verifies both master and slave cores, with transmit and receive streams operating full-duplex at 50MHz of SPI clock.

This circuit also includes a very robust debouncing circuit to use with multiple inputs. The model, "grp_debouncer.vhd" is also published under a LGPL license.
