PODEM

An algorithm used ATPG
popularity

Description

PODEM (Path-Oriented Decision Making) is an Automatic Test Pattern Generation (ATPG) algorithm, created to overcome the limitations of the D-Algorithm (D-ALG) in the generation of test vectors for circuits involving error correction and translation. It was developed by Dr. Prabhu Goel.

The D-ALG is ineffective in generation of test vectors for circuits that use XOR gates with re-convergent fan-outs. This kind of circuit is commonly used in applications requiring Error Correction and Translation (ECAT).
