Hi...

I have 3 modules ...
1) Encoding
2)PISO
3)Decoding

My implementation of 3 modules in VHDL is over. Now i want to design 1 main FSM which will control my whole process by using three modules.

I dont know how to do this???

I dont know how to implement FSM in which 3 different modules are present. So can anybody know how to do it??
 

well, first of akll you need to know how the 3 modules operate individually, so the FSM can control them. but why cant you run all 3 modules in parrallel (ie pipelined)?

i know operation of each module wel.
what do you mean actually parallel(pipelined)?
 

Well, your first post is not very clear. Do these three modules work together? or do they operate depending on some condition? or what.

Without much detail, its very hard to answer your question.

they operate with some conditions. but these modules depend on each other.
i can say i want to port-map 3 modules to perform certain functionality. but my task is that to do using FSM.
so how can do this?
 

Your problem is the thing in the module is not working correctly. You fix this by fixing the thing in the module, such that it will work correctly. After that your problem will be solved.

Hope this generic message with generic instructions will help you fix your generic problem described in a non-detailed generic fashion. :)

Anyways, make module with FSM. Instantiate the 3 modules inside this same module. Connect control signals from FSM to modules. Need more detail? Provide more detail. :)

My three modules are working correctly.

But i want to instantiate three modules in a single system and control it using FSM. i know to design FSM, but i never tried FSM on modules to control.
can u help?

That's not "more detail", that's a rehash of the stuff you already said. But no worries, maybe someone else can extract the needed information from it to help you...
