Connecting components together using HDL is not difficult.

More Questions from Flip-Flops

• VHDL was created as a very flexible language and it allows us to define the operation of clocked devices in the code without relying on logic primitives.
• A gated S-R flip-flop goes into the SET condition when S is HIGH, R is LOW, and EN is HIGH.
• All multivibrators require feedback.
• Most basic latches and flip-flops are available in IC packages of eight latches or flip-flops with a common clock.
• The 7475 is an example of an IC D latch (also called a bistable latch) that contains four transparent D latches.
• VHDL does require a special designation for an output with a feedback.
• Pulse-triggered flip-flops are identified by a bubble on the Q output terminal.
• Edge-triggered J-K flip-flops make it hard for design engineers to know when to accept input data.
• The propagation delay time tPLH is measured from the triggering edge of the clock pulse to the LOW-to-HIGH transition of the output.
• A TOGGLE input to a J-K flip-flop causes the Q and outputs to switch to their opposite state.
