Testing of Level Shifters in Multiple Voltage Designs
Testing of Level Shifters in Multiple Voltage Designs
The use of multiple voltages for different cores is becoming a widely accepted technique for efficient power management. Level shifters are used as interfaces between voltage domains. Through extensive transistor level simulations of resistive open, bridging and resistive short faults, we have classified the testing of level shifters into PASSIVE and ACTIVE modes. We examine if high test coverage can be achieved in the PASSIVE mode. We consider resistive opens and shorts and show that, for testing purposes, consideration of purely digital fault effects is sufficient. Thus conventional digital DfT can be employed to test level shifters. In all cases, we conclude that using sets of single supply voltages for testing is sufficient.

Abstract
The use of multiple voltages for different cores is becoming a widely accepted technique for efficient power management. Level shifters are used as interfaces between voltage domains. Through extensive transistor level simulations of resistive open, bridging and resistive short faults, we have classified the testing of level shifters into PASSIVE and ACTIVE modes. We examine if high test coverage can be achieved in the PASSIVE mode. We consider resistive opens and shorts and show that, for testing purposes, consideration of purely digital fault effects is sufficient. Thus conventional digital DfT can be employed to test level shifters. In all cases, we conclude that using sets of single supply voltages for testing is sufficient.
