Advanced Level - 4 daysview dates and locations
Expert Verilog is an intensive 4-day advanced application course. It teaches engineers how to increase productivity by enhancing their Verilog coding and application skills. Presented in two distinct modules, Expert Verilog focuses on language and synthesis issues, design re-use, test benches and the latest verification techniques – including PSL and an introduction to modern assertion-based approaches to verification. Each module also includes an overview of the 2001, 2005 and SystemVerilog extensions to Verilog, with an assessment of their impact on both design and verification.
- Expert Verilog Design (2 days) for design engineers wishing to deepen their knowledge of both RTL and synthesis using Verilog, and to improve their Verilog coding style with design re-use in mind. Design for Verification is also covered with an Introduction to PSL and modern assertion-based techniques.
- Expert Verilog Verification (2 days) for design engineers and verification engineers involved in Verilog test bench development, or behavioural modelling, for the purpose of functional verification.
The modules, which may be attended together or independently, follow on from the industry standard Doulos course, Comprehensive Verilog. Carefully designed workshops comprise 50% of teaching time, and enable engineers to apply their new skills in the context of the latest Verilog design tools, practices and methodologies.
Who should attend?
- Design engineers wishing to improve the efficiency of their hardware designs and increase productivity
- Design and verification engineers who want to structure and write effective test environments to verify complex designs and systems
What will you learn?
- A deeper understanding of the Verilog language and how to apply it, enabling you to troubleshoot Verilog simulation and synthesis problems more easily.
- How to produce smaller and faster hardware designs using Verilog with RTL synthesis tools.
- A Verilog coding style to facilitate code re-use and best practice in how to package IP.
- How recent revisions of the Verilog language and the SystemVerilog extensions will impact and enhance your design and verification activity
- How best to tackle the problem of design verification using Verilog - the principles and practice.
- Techniques for writing behavioural models of hardware components in Verilog.
- How to incorporate PLI applications into your Verilog simulations.
Pre-requisitesThis is an advanced language and methodology training course. Prior attendance of the Doulos Comprehensive Verilog course (or equivalent) is required, and at least 6 months of 'live' project experience using Verilog is strongly recommended. Delegates attending the Expert Design module must have knowledge and experience of register transfer level coding and synthesis, using Verilog.
