Functional Description:
The RS Flip-Flop is a logic gate that sets its output HIGH if both the S ("set") input is HIGH and the R ("reset") input is LOW. The flip-flop resets its output to LOW if input R is HIGH and input S is LOW. If both S and R are LOW, the output does not change. If, both S and R are HIGH, the output will switch state. The truth table for the operator is:

R	S	y(t)
LOW	LOW

LOW	HIGH	HIGH

HIGH	LOW	LOW

HIGH	HIGH

In the table, y represents the output, R is the reset input, S is the set input, and (delta)t is the loop sampling time.
Design Pad will issue an error on processing if an 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.
