 Auf Deutsch

Comprehensive Verilog is a 4-day training course teaching the application of the Verilog® Hardware Description Language for FPGA and ASIC design. The syllabus covers the Verilog language, coding for register transfer level (RTL) synthesis, developing test fixtures, and using Verilog tools in the FPGA or ASIC design flows. For those interested in FPGA design or prototyping, depending on your choice of FPGA vendor and course venue, we can teach you the complete design flow from writing Verilog source code down to programming a physical FPGA demo board.

The course includes a brief overview of SystemVerilog, but delegates wishing to learn SystemVerilog in depth should attend Comprehensive SystemVerilog or Modular SystemVerilog

Workshops comprise approximately 50% of class time, and are based around carefully designed exercises to reinforce and challenge the extent of learning.

Doulos is an independent company, enabling delegates to receive the benefit of objective tuition while learning in the context of their chosen tool and methodology. Leading tools supported by this course include:

    Simulation
  • Aldec Active HDL™ & Riviera-PRO™
  • Cadence Incisive®
  • Mentor Graphics ModelSim® & Questa®
  • Synopsys VCS®
    Synthesis
  • Synopsys Synplify Pro®
  • Synopsys Design Compiler®
  • Mentor Graphics Precision® RTL

The course includes specific lab support for tool sets from the leading FPGA vendors including the vendor's native simulation and place-and-route tools.

The tool options available on a specific scheduled course may vary. Preferences can be selected in the booking process. Or please contact Doulos to discuss specific requirements.

Who should attend?

  • Engineers about to embark on their first Verilog design project
  • Engineers who have already acquired some practical experience in the use of Verilog, but wish to consolidate and extend their knowledge within a formal training environment using the tools of their choice.

What will you learn?

  • How Verilog fits into the FPGA or ASIC design flow
  • How to use the Verilog language for hardware design and logic synthesis
  • How to write thorough Verilog text fixtures to verify your designs
  • How to avoid common mistakes when coding Verilog for synthesis
  • How to use the specific Verilog tool flow you will be using on your project for simulation, synthesis, and where appropriate, FPGA P&R.

Pre-requisites

Delegates should have a good working knowledge of digital hardware design, or have attended Essential Digital Design Techniques (or equivalent). No previous Verilog knowledge is required.

Course materials
