Comprehensive Verilog

Standard Level - 4 days

 Auf Deutsch

Comprehensive Verilog is a 4-day training course teaching the application of the Verilog® Hardware Description Language for programmable logic and ASIC design.

The syllabus covers the Verilog language, coding for register transfer level (RTL) synthesis, developing test fixtures, and using Verilog tools. The course also provides an overview of SystemVerilog.

Because Doulos is independent, delegates can usually use their choice of design tools during the workshops. Workshops are based around carefully designed exercises to reinforce and challenge the extent of learning, and comprise approximately 50% of class time.

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.
• Engineers who are proficient in VHDL but need to become competent in the application of, and interaction with, Verilog HDL as well

What will you learn?

• How Verilog fits into the FPGA/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

Pre-requisites

Delegates must have attended Essential Digital Design Techniques (or equivalent), or have a good working knowledge of digital hardware design. No previous knowledge of VHDL or software language experience is required.

Course materials

Doulos Course materials are renowned as the most comprehensive and user friendly available. Their style, content and coverage is unique in the HDL training world and has made them sought after resources in their own right. Course fees include:

• Fully indexed course notes creating a complete reference manual
• Workbook full of practical examples to help you apply your knowledge
• Doulos Golden Reference Guide for Verilog language, syntax, semantics and tips
• Tool tour guides (to support the tools and technologies of your choice).
