PPT-ATE Test Time Reduction by Scaling Voltage and Frequency

Praveen Venkataramani Advisor Vishwani D Agrawal Problem statement Test is not free Test time is proportional to test cost Scan based test clock period is limited by the maximum power consumed . Electrical Science. Chapter 10: Sinusoidal Steady-State Analysis. Linear circuits with sinusoidal inputs that are at steady state are called ac circuits, . e.g. , the power system that provides us with electricity can be considered a very large ac circuit. J. .
