How to Code a State Machine in Verilog

  1. Stepper motor controller state diagram.
  2. This block of code creates the state variables.
  3. This block of code creates the state registers that hold the next_state and present_state variables.
  4. This is the first chunk of the state logic.
  5. This is the second chunk of the next state logic.

How many gates are required for m * n array multiplication?

Therefore, for an m x n Array Multiplier, m*n AND gates, n HAs, (m-2)*n FAs, i.e. a total of (m-1)*n adders are required.

What is n-bit multiplier?

In general, an N Ă— N multiplier multiplies two N-bit numbers and produces a 2N-bit result. The partial products in binary multiplication are either the multiplicand or all 0’s. Multiplication of 1-bit binary numbers is equivalent to the AND operation, so AND gates are used to form the partial products.

What is n bit multiplier?

What are the different types of FSM?

An FSM is defined by a list of its states, its initial state, and the inputs that trigger each transition. Finite-state machines are of two types—deterministic finite-state machines and non-deterministic finite-state machines.

How to implement n-bit adder in Verilog co-processor?

This post presents Verilog code for N-bit Adder designed for the co-processor. The Verilog code for N-bit Adder is done by using Structural Modeling. As shown in the above picture, the N-bit Adder is simply implemented by connecting 1 Half Adder and N-1 Full Adder in series.

How does the Verilog multiplier work?

Full Verilog code for the multiplier is presented. The technique being used is shift/add algorithm, but the different feature is using a two-phase self-clocking system in order to reduce the multiplying time by half. As soon as the start signal is asserted, the multiplier begins to perform the multiplication.

Is 4-bit counter implemented in Verilog?

Last time , several 4-bit counters including up counter, down counter and up-down counter are implemented in Verilog. Verilog code for t…

What is synchronous finite state machine (FSM)?

Designing a synchronous finite state machine (FSM) is a common task for a digital logic engineer. A finite state machine can be divided in to two types: Moore and Mealy state machines. Fig. 1 has the general structure for Moore and Fig. 2 has general structure for Mealy.
