Xilinx-ise, invert input?

May 19, 2006 3 Replies

How does one modify say a 'fdcp' block/object such that PRE & CLR is inverted..? without resorting to adding external inverters.


So if I want an asynchronous flip-flip with D, Q, _Q, CLK, _PRE, _CLR as one "symbol" in schmatic. How do I accomplish this ?

write VHDL wrapper around the components, implement there inversion and convert to schematic symbol
