ATPG for Sequential circuits

Automatic Test Pattern Generation and Automatic Test Pattern Generator (ATPG) is an electronic design automation method/technology used to find an input (or test) sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects. Earlier we presented a tutorial on ATPG for Combinational Circuits. This tutorial focuses on ATPG for sequential circuits

Code Coverage

Code coverage is a basic coverage type which is collected automatically. It tells you how well your HDL code has been exercised by your test bench. In other words, how thoroughly the design has been executed by the simulator using the tests used in the regression. Functional coverage measures how well the functionality of the
