A test method and test codes generator for improved HT Fault Model based on NoC

摘要

NoC is a expand for SoC. The architecture of NoC is huge and complex, it leads to the crosstalk fault between internal transmission of NoC increasingly serious. Crosstalk serious impact on the signal integrity of on-chip system. A new test codes generator was designed by PSpice simulation software based on improved HT model. The generator was composed of a 16-bit counter and a 16-bit data selector. The generator was tested by PSpice software, the result showed that it satisfied the test requirements and had the advantage of portable. A crossstalk test method was proposed in this paper, we used this method on a test circuit, the result showed that the method could reduce the number of tests and save resource effectively.
