Verification of Robot Controller for Evaluating Impacts of Faults in Electro-mechanical Systems

Functional verification is a modern approach to verifying that digital system complies with its specification. Verification environment for functional verification of robot controller which searches path for the robot through maze is presented in this paper. This verification environment is designed according to the UVM (Universal Verification Methodology) principles. As an interesting feature of the verification environment we see the use of mechanical part (robot in a maze) simulation. The article describes the use of the verification environment for evaluating impacts of faults in electro-mechanical systems. The experimental results gained from the verification process are also presented in the paper. The verification environment will serve as a tool for automating fault tolerance evaluation of electro-mechanical systems and together with the fault injector will form the basis of the verification platform in the future.
