Abstract

A method and circuit for implementing Efuse sense amplifier verification, and a design structure on which the subject circuit resides are provided. A first predefined resistor value is sensed relative to a reference resistor. A second predefined resistor value is sensed relative to a reference resistor. Responsive to identifying a respective sense amplifier output resulting from the sensing steps of an unblown eFuse and a blown eFuse, valid operation of the sense amplifier is identified.
