Unique Style To Achieve A Built-In Self-Test (The Best) Is Possible Uart By Ca-Lfsr

Abstract

In today's life the manufacturing process is very complicated, including considering industries The test capability as a condition to ensure the reliability of the functions of each of the departments that have been designed. One of the It is called built in the most popular autonomous test techniques, test (the best). The best is a design that allows style To test the system itself automatically with the somewhat larger size of the system. Universal Asynchronous Receiver and Transmitter (UART) with the ability to enable the beast has a UART test target on the same chip and not External devices are required to perform the test. This document focuses on the (pattern generator) test of the TPG circuit From Best, in this document, performance as a result of the simulation is achieved by allowing the BIST architecture through UART VHDL programming sufficient to compensate for the additional hardware required in the beast architecture. East The generation of random test technical pattern automatically, so it can provide less trial time compared to the outside Applied test pattern and helps to achieve higher productivity both at the end.
