Implementation of SPI/I2C/Mux-Demux logic for MULTIDUT Setup for SoC Characterization

Abstract

Testing of product is a very vital role for any company before launching of the product. Half measure in testing can directly affect the trust of people on product and company. As time to market ratio also should be maintained by every company to get its product launch before any other company with the requirements customer needs. MULTIDUT setup provides saving in time with validation testing for Bluetooth technol- ogy and reduce or almost kill the requirement to go to major chambers or labs to change the modules and do the testing. MULTIDUT Setup has its own controller as PSoC which controls CPLD to control the DUT and perform the operations. CPLD can control the blocks like DAC, EEPROM, etc. which is required for a DUT to control for the testing. PSoC controls CPLD to fire the commands and do the needed testing like Regression, PVT, etc. on the given DUT. Basic aim of the project is to reduce the human effort needed and giving the product to the customers with reduction of time of testing without compromising the quality of the product.
