Draw the RTL diagram for a Class-1 FSM.
Codeword feed-forward only
Draw the RTL diagram for a Class-2 FSM.
Codeword feedback, output without external input
Draw the RTL diagram for a Class-3 FSM.
Codeword feedback, external input
Draw the RTL diagram for a Class-4 FSM
Codeword feedback, external input, I/O bypass
How can we build larger scale (potentially many input) FSMs?
Using modularity and linking several FSMs. They are all synchronised by having a common clock signal.
How do you represent a state in an ASM chart?
A rectangle containing the active outputs with an ellipse to the top left containing the state name.
How do you represent a transition decision in an ASM chart?
With a diamond box containing the variable (input) and a path for each outcome 0 or 1.
How do you represent a simple state-to-state transition in an ASM chart?
A simple arrowed line
What is modulation in FSMs?
We can split a problem into several FSMs (represented by ASM charts) connected by an output/input pair.
