Hi,

I want to make a block-based design using megafunctions and other primitives of QuartusII 3.0. The design is to dived a bits stream to even bits stream and odd bits stream. / d0,d2,d4,... d0,d1,d2,d3,d4,d5... / \ \ d1,d3,d5,... Please give me some hints.

Thanks

How about a counter on rx_clk running 0,1,0,1,0,1,... with its Q going to shiftA enable and not Q going to the shiftB enable. Both shifters also on rx_clk.

Note that you don't need to bother with megafunctions for shifters and counters.
