Functional Description:
The D Flip-Flop or "Delay" Flip-Flop is a logic gate with one-bit memory. It toggles its output whenever its input value switches from LOW to HIGH; otherwise, the output value remains unchanged. The operator has the following truth-table:

x(t)	x(t-t)	y(t)
LOW	LOW

LOW	HIGH

HIGH	LOW

HIGH	HIGH

In the table, y is the output, x is the input, and (delta)t is the loop sampling time.
Design Pad will issue an error on processing if the input pin is not connected.

User-Defined Properties:
Object Name. A string label that identifies the operator

Initial State. The output state (HIGH or LOW) on startup (at time t=0)

Comments: None.
