Example of Fewer Input Pins than EDIF Input Ports

In this example, only the A<0> and B<0> ports of the LS21 function are mapped onto the AND2 primitive. The C<0> and D<0> ports must not be driven by signals within the EDIF Input File (.edf). A signal that drives an unmapped pin is reported as a node without a destination.

BEGIN
   FUNCTION     and2	(IN1, IN2, , )
      RETURNS	        (OUT)
    FUNCTION	"LS21"	("A<0>", "B<0>", "C<0>", "D<0>")
      RETURNS		("Y<0>")
END
