Intermediate VHDL Coding for Synthesis
Intermediate Level. 2 Days: 50% Lecture, 50% Labs

Course Overview
An in-depth study of VHDL coding styles, methodologies, and design techniques used to efficiently synthesize digital hardware (ASICs and FPGAs).

Class topics focus on mapping digital hardware structures to vendor independent VHDL code. Detailed do's and don'ts of synthesis coding styles are discussed. Lecture and laboratory materials illustrate the optimization differences achieved by different VHDL coding styles. Students will learn proven coding practices that result in smaller and faster designs.

Synthesis coding styles recommended in this course are also recommended by IEEE standard 1076.6, Standard For VHDL Register Transfer Level Synthesis. As a result, no matter whose synthesis tool you use, the synthesis coding styles and techniques you learn will yield effective results.

This class is the first half of VHDL Coding for Synthesis

Intended Audience
The numerous examples in this course make it suitable for a student with limited VHDL. The application focus of this course results in the student being ready for VHDL based ASIC or FPGA design.

Course Objectives
Upon completion of this course, students will be able to:
  • Write efficient, vendor independent VHDL code
  • Use best coding styles and practices to create ASIC and FPGA logic
  • Understand and avoid problematic hardware coding styles
  • Use code templates to create a design from the block diagram
  • Read VHDL code and draw the corresponding hardware (reverse engineer)
  • Use types, overloading, and conversion functions from standard VHDL packages (std_logic_1164, numeric_std, and std_logic_arith)
