The BusMatrix conforms to the following AMBA timing parameters:
combinatorial input to output paths less than 20% of HCLK cycle
all outputs valid 60% of cycle after rising HCLK
registered inputs setup 60% of cycle before rising HCLK.
The timing characteristics are confirmed by performing synthesis on the slave switch using the slow/slow process point of the Avanti cb25 cell library at a target speed of 100MHz.
