Test Compression - VLSI Tutorials
Embedded Deterministic Test (EDT) One of the most common hardware test compression technique is EDT. Tessent TestKompress is the tool that can generate the decompressor and compactor logic at the RTL level.
Using EDT Test Points to reduce test time and cost
2015年9月24日 · One new method for scan test that fits the bill as a potential new standard of practice is called “Test Points for embedded deterministic test” (EDT). The use of test points to improve test coverage has been available for a long time, but the new EDT Test Points are unique in their ability to reduce pattern count and hence test time.
DFT reduces test set sizes. — Reduces ATE memory requirements — Reduces test time — Minimizes or eliminates tester reloads — Improves tester throughput. Tester Capacity Limit.
Embedded deterministic test (EDT) is a manufacturing test paradigm that combines the compression advantage of built-in self-test with the high fault coverage of deter-ministic stimuli inherent to methods based on automatic test pattern generation and external testers. Despite enabling the use of low cost testers for rapidly achieving

Lower test time and pattern count. Built on the patented Embedded Deterministic Test (EDT) technology, Tessent TestKompress reduces both test time and pattern volume by several orders of magnitude without any loss in fault coverage.
Test Coverage Analysis of DFT with EDT and without EDT Architecture
EDT (Embedded deterministic testing) is employed in order to reduce the test volume and reduced ATE memory usage due to large number of test patterns. This paper aims to determine, how well the EDT architecture performs in a DFT environment in terms of coverage for atspeed and stuck at fault model.
Embedded deterministic test (EDT) architecture.
In this paper, we develop novel design-for-testability (DFT) structures to considerably reduce the cost of initializing the circuit during functional test.
