VHDL: Implementing the XC3000/XC4000 readback function.


Problem Description:
How to implement the Readback function in VHDL ?


Solution 1:




The following is an example instantiation of the readback
function in VHDL. This example assumes that the readback
clock is cclk.

entity readbk is
  port(trig: in bit;
       data, rip: out bit);
end readbk;

architecture inst of readbk is

  component RDBK
   port(trig: in bit;
        data, rip: out bit);
  end component;

begin

  U1: RDBK port map(trig, data, rip);

end inst;
