The general form of an entity looks like this: How to create a Finite-State Machine in VHDL Saturday, Aug 25th, 2018 A finite-state machine (FSM) is a mechanism whose output is dependent not only on the current state of the input, but also on past input and output values. 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. 9.8.

It is conceived as an abstract machine that can be in one of a finite number of user-defined states. The machine is in only one state at a time; the state it is in at any given time is called 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. Or it can be split up into one synchronous process and one or two combinatorial processes. Namely the two-process or three-process state machine. In VHDL, Finite State Machines (FSMs) can be written in various ways. This article addresses the encoding of, and the data types used, for the state register.

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 from FSM to VHDL by our tool.

9.8. When to use FSM design¶ We saw in previous sections that, once we have the state diagram for the FSM design, then the VHDL design is a straightforward process. But, it is important to understand the correct conditions for using the FSM, otherwise the circuit will become complicated unnecessary. In VHDL, Finite State Machines (FSMs) can be written in various ways. This article addresses the encoding of, and the data types used, for the state register .

As we have mentioned before, Synthesis tools usually understand only a subset of the VHDL language. Let us use an example to see how we write VHDL for FSM that can be synthesized easily. We will use a controller for a CPU as an example.

This book by Dr. Pedroni is a first of a kind comprehensive treatment of FSM hardware design covering examples in VHDL and SystemVerilog. It covers important

VHDL Coding of FSM : VHDL contains no formal format for finite state machines. A state machine description contains, a state variable, a clock, specification of state transitions, specification of outputs and a reset condition.
