Reducing Chip Test Costs With AI-Based Pattern Optimization

The old adage “time is money” is highly applicable to the production testing of semiconductor devices. Every second that a wafer or chip is under test means that the next part cannot yet be tested.

What’s The Difference Between Scan ATPG And IJTAG Pattern Retargeting?

Both scan automated test pattern generation (ATPG) patterns and IJTAG patterns 1,2,3 are created for a piece of logic that is part of a much larger design. For both, the patterns are independent from ...

Using Timing Constraints For Generating At-Speed Test Patterns

Handling timing exception paths in ATPG tools while creating at-speed patterns has always been a tough and tricky task. It is well understood that at-speed testing is a requirement for modern ...
