Low Power Programmable PRPG with the Test Compression Capabilities

Abstract

This paper presents a low power pseudo random sample generator with desired preselected toggling activity. The proposed structure has a linear comments shift sign in or a ring generator (linear finite nation machine) which drives section shifter and it produces binary sequences with low switching price. This could have the first-class test insurance possible in comparison with the great-to-date conventional BIST-primarily based PRPGs. In this proposed gadget we introduce with negligible effect on check application time and deterministically manual the take a look at pattern generator toward test sequences with the intention to enhance the ratio of fault-coverage-to sample-count number. The above proposed hybrid system successfully combines test compression with Logic BIST to supply high high-quality tests. The gadget is applied the usage of HDL and the simulation and synthesis reports are shown.
