Design of Pseudorandom Pattern Generator for MIHST
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
The paper describes a system generator which produces Pseudo random sequence with user defined toggling range. The patterns were generated using PRPG; Detection of errors is done using Microprocessor Hardware Self Test (MIHST) for each pattern produced by generator. The MIHST is a permutation of BIST and SBST principles. A method is introduced for mechanical selection of some control signals of generator offering simple and exact tuning. The main intend is that due to PRESTO (pre-selected toggling level) switching activity for the period of scan loading is reduced. Using Micro processor hardware self test unit processor executes compact test sequences like SBST. Microprocessor Hardware Self Test is mainly used for processors online test rooted on system-on-chip, it overcomes limitations of SBST. The major benefit of MIHST is it utilizes less resources compared to SBST. The MIHST reduces time essential for the execution by removing instructions necessary for the test flow management.
