A pure FSM cannot "count" anything in the states. A counter is an FSM by itself. In order to delay N cycles in a specific state, you will need to expand it to N+1 substates, which will "count" the delay transitions. Of course you can compromise the "purity" of the FSM and add a counter as you mention. You can find a plenty of examples of the

This tutorial accompanies Lab 6: Finite State Machines and VGA Controller. Background Information The most apparent difference between FSMs written in VHDL, is the number of processes used. The FSM may be implemented entirely in one clocked process.

The FSM can be also encoded with a single process, but the FSM VHDL template proposed is used to make the code more linear and readable. For example, you can find the similar template in the Xilinx XST user guide page 250. Note that the present state is stored in registers while the next state is completely combinatorial.

Selecting "User" as the FSM Encoding Algorithm maintains the constant-value state assignments coded in the design source. FSMs in VHDL expressed using enumerated type are also recoded according to the GUI selection.

Essential VHDL for ASICs 108 State Diagram for header_type_sm All your state machines should be documented in roughly this fashion. The name of the process holding the code for the state machine is the name of the state machine. In this case it is header_type_sm. Every state machine has an arc from “reset”. This indicates what state the state

Whenever you need to create some sort of time-dependent algorithm in VHDL, or if you are faced with the problem of implementing a computer program in an FPGA, it can usually be solved by using an FSM. The first step in writing the VHDL for this FSM is to define the VHDL entity.
