An efficient technique for processor automatic functional test generation based on evolutionary strategies
Ján Hudec · Information Technology Interfaces · 2011
This paper presents some results in the design and implementation of a universal functional test generator for VLSI circuits, such as microprocessor and processor cores. Our approach to test generation - the functional test generation method - is based on knowledges of instruction set architecture (ISA), functional description of VLSI systems at functional VHDL level and promising concept of software-based self test (SBST); for better test generation the genetic algorithm (GA) properties based on evolutionary strategies are used. The algorithm for automatic generation of functional test of processors (normal executable test sequence of instructions) is used in very flexible and effective tool - Automatic Functional Test Generator (AFTG). The determination of the test efficiency of instruction testing mixes is also discussed.
