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 ...

What’s The Difference Between ATPG And Logic BIST?

Two test strategies are used to test virtually all IC logic: automatic test pattern generation (ATPG) with test pattern compression and logic built-in self-test (BIST). This article will describe how ...

Squeezing Out More Test Compression

The trend in semiconductors leads to more IC test data volume, longer test times, and higher test costs. Embedded deterministic test (EDT) has continued to deliver more compression, which has been ...

A Simple Way To Improve Automotive In-System Test

Test points for hybrid ATPG/LBIST applications make it easier to reach the ISO 26262 standard of 90% stuck-at coverage for in-system test. The remarkable growth in automotive IC design has prompted a ...
