State machine
Dear all,

I would like to ask how can I draw a state machine from the logic relation I have??
For exmaple, if I would like to draw a state machine for the following two relationships, what should the states be? and how to connect between different states?? Thanks.

Relationships:

C <= A AND B
E <= C OR A

State machine
the logic equation u provide is a combinational logic... so it dont need statemachine which is required for sequential logic...

why u need the 2 equations to b state machine?

regards,

Re: State machine
hi, sp

Since I have just written a program for my project, and I use combinational logic. However, in the report of this project, it requires me to give them a state machine. So, I am wondering how to draw state machines for my combinational logic codes. But if state machine cannot be drawn for combinationla logic, that doesn't matter. I will not change my codes~~ Smile

State machine
You can draw a state machine from your equations, but it will only have one state.

State machine
i think u make a mistake... no one will ask u to do FSM for a combinational logic...

read ur question again...

Re: State machine
FSM is not used for combinational logic. but if you want two learn how to creat an FSM you can reffer to Matlab software and its help.
