Output code has “hand-coded” look-and-feel (no tasks, functions, etc). Switch between highly encoded or onehot output without changing the source. Registered outputs can be specified to be included as state bits, or pulled out as independent flops. Designing State Machines for FPGAs A six-state state machine requires a six-bit shift register with one register per state. Using this shift register determines the state sequence map of the state machine. The state machine creates the three output bits based on decoding the outputs of the shift register.

Implementing State Machines (VHDL) A state machine is a sequential circuit that advances through a number of states. To describe a state machine in Quartus II VHDL, you can declare an enumeration type for the states, and use a Process Statement for the state register and the next-state logic. architecture behavior of sm_vhdl is type state_type is (a, b, c); signal state : state_type; begin process(clock, resetn) begin if resetn = '0' then state <= a; elsif clock'event and clock = '1' then case state is when a => case x is when "00" => state <= b; end case; case x is when "01" => state <= a; end case; case x is when "10" => state <= a; end case; case x is when "11" => state <= c; end case; when b => case x is when "00" => state <= b; end case; case x is when "01" => state <= a State Table. Use two processes – one for the combinational logic and one for the state register. Add an asynchronous reset input. Simulate the VHDL code and verify that it works correctly.

Rising edge detector generates a tick for the duration of one clock cycle, whenever input signal changes from 0 to 1. In this section, state diagrams of rising edge detector for Mealy and Moore designs are shown. Then rising edge detector is implemented using VHDL code. The FSM diagram, the VHDL code, and the waveform are all related to the Moore machine.

Always explicitly define behaviour for all states and outputs. If not, the results of synthesis may produce unexpected results. It is generally suggested that one-hot encoding be used for state machines. For example, a 5 state machine should use 5 bits to encode the states. Each state should have one bit high and the others low.
