Description
The Design-for-Test: Scan and ATPG course is designed to drive the development of your skills and knowledge in scan and ATPG design processes utilizing Mentor Graphics tools: DFTAdvisor, FastScan, , MacroTest, DFTInsight and ModelSim®.
This course teaches you how to insert full scan in a design using the DFTAdvisor tool flow, and shows you how to create high quality test patterns using the FastScan tool flow.
The hands-on labs are designed to reinforce key concepts through practical experience and to develop proficiency with Mentor Graphics DFT tool suite under the guidance of our industry-expert instructors.
You will learn how to
- Configure scan chains/test logic and insert full scan
- Understand ATPG messaging
- Achieve high test coverage
- Create high quality patterns
- Understand advanced test methodologies
- Troubleshoot areas of low test coverage
- Troubleshoot DRC and simulation mismatch
