IMPORTANT: This is a condensed, 2-day version but supplies the complete information normally delivered in 3-day course.

Course Description 

This course provides a thorough introduction to the VHDL language.

The emphasis is on:

  • Writing efficient hardware designs
  • Performing high-level HDL simulations
  • Employing structural, register transfer level (RTL), and behavioral coding styles
  • Targeting Xilinx devices specifically and FPGA devices in general
  • Utilizing best coding practices

 

 

* This course does not focus on any particular architecture. Check with your local Authorized Training Provider for the specifics of the in-class lab board or other customizations.

After completing this comprehensive training, you will have the necessary skills to:

  • Implement the VHDL portion of coding for synthesis
  • Identify the differences between behavioral and structural coding styles
  • Distinguish coding for synthesis versus coding for simulation
  • Use scalar and composite data types to represent information
  • Use concurrent and sequential control structure to regulate information flow
  • Implement common VHDL constructs (finite state machines [FSMs], RAM/ROM data structures)
  • Simulate a basic VHDL design
  • Write a VHDL testbench and identify simulation-only constructs
  • Identify and implement coding best practices
  • Optimize VHDL code to target specific silicon resources within the Xilinx FPGA
  • Create and manage designs within the Vivado Design Suite environment

 

Course Outline

Day 1

  • Introduction to VHDL

Discusses the history of the VHDL language and provides an overview of the different features of VHDL. {Lecture}

  • VHDL Design Units

Provides an overview of typical VHDL code, covering design units such as libraries, packages, entities, architectures, and configuration. {Lecture, Lab}

  • VHDL Objects, Keywords, Identifiers

Discusses the data objects that are available in the VHDL language as well as keywords and identifiers. {Lecture}

  • Scalar Data Types

Covers both intrinsic and commonly used data types. {Lecture}

  • Composite Data Types

Covers composite data types (arrays and records). {Lecture}

  • VHDL Operators

Reviews all VHDL operator types. {Lecture}

  • Concurrency in VHDL

Describes concurrent statements and how signals help in achieving concurrency. {Lecture}

Describes how to interact with a simulation via text I/O. {Lecture}

  • Finite State Machine Overview

Provides an overview of finite state machines, one of the more commonly used circuits. {Lecture}

  • Mealy Finite State Machine

Describes how to implement a Mealy state machine in which the output is dependent on both the current state and the inputs. {Lecture}

  • Moore Finite State Machine

Demonstrates how to implement a Moore state machine in which the output is dependent on the current state only. {Lecture, Lab}

  • FSM Coding Guidelines

Describes the guidelines and recommendations for using one or more procedural blocks when coding a finite state machine. {Lecture}
