SOFTWARE BASED TESTING OF MICROCONTROLLER USING REAL TIME OPERATING SYSTEM

Abstract

Microcontrollers have made their way into embedded applications such as automobile electronics, industrial automation and
peripherals for computer systems. For the microcontroller to perform efficiently it is necessary for a test engineer to check the proper
operation of a product. Manufacturing test is one of the most difficult tasks in the semiconductor industry. This paper presents a
novel approach for testing a microcontroller with software based tests using RTOS (Real Time Operating System). The methodology
exploits existing manufacturing test programs designed for software based self test and enhances them by using a new approach with
RTOS. Experimental results are reported in this paper showing the reliability and effectiveness of the method in detecting faults in a
microcontroller.
