Download this article in PDF format. Finding the right balance among test cost, test quality, and data collection for running diagnosis requires consideration of several competing factors. Luckily ...
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 ...
Chip testing has become increasingly complex due to the number of variables impacting designs – from design size and complexity, to high transistor counts on advanced technology nodes, to 2.5D/3D ...
Patterns created using advanced fault models provide higher test coverage, improved defect detection, and higher-yielding ...
In New test points slash ATPG test pattern count, I described a new type of test point technology used with scan compression for device testing. The key benefit of using test points with embedded ...
Scan insertion to improve test coverage and reduce test pattern volume is very common in today’s DFT tools. All of the major ATPG tool vendors (Synopsys, Cadence, and Mentor) offer this approach in ...
[Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one is checking ...
