Latch Timing Diagram. Complete the timing diagram showing the state of the q output over time as the set and reset switches are actuated. Using boolean and registered logic equations written in vhdl verilog or synapticads syntax you can describe signals in terms of other signals in the diagram.
The name data latch refers to a d type flip flop that is level triggered as the data 1 or 0 appearing at d can be held or latched at any time whilst the ck input is at a high level logic 1. Circuit diagram of a d flip flop is shown below. As can be seen from the timing diagram shown in fig 532 if the data at d changes during this time the q output assumes the same logic level as the d.

Waveformer pro datasheetpro verilogger and testbencher pro have a built in interactive hdl simulator that greatly reduces the amount of time needed to draw and update a timing diagram. Draw a timing diagram for this circuit assuming that the propagation delay of the latch is less than the clock pulse width. At time a s goes high and sets q which remains high until time b when s is low and r goes high resetting q. Latches are said to be level sensitive devices.
