Abstract
A system and method for identifying a location of a short in a circuit of a semiconductor device is disclosed. The method and system includes providing a power supply and providing a power distribution network coupled to the power supply. The power distribution network is for distributing power to a portion of the circuit. The power distribution network further including means for selectively disconnecting a portion of the power distribution network. The portion of the power distribution network supplies power to the location of the short.
Claims4
A system for identifying a location of a short in a circuit of a semiconductor device, comprising:
- a power supply;
- and
- a power distribution network coupled to the power supply for distributing power to a first portion of the circuit, the power distribution network further including means for selectively disconnecting each of a plurality of portions of the power distribution network, each of the plurality of portions of the power distribution network supplying power to a second portion of the circuit, a particular portion of the plurality of portions of the power distribution network supplying power to the short, the power distribution network being integrated into a semiconductor die;
- wherein the power distribution network, the means for selectively disconnecting and the circuit reside on the semiconductor die.
