Abstract: A CoDec in a design for test integrated circuit. In embodiments described herein, portions of the CoDec are distributed over the area of the IC. In particular, both the compressor and the decompressor may be distributed over the IC. To this end, XOR gates are located locally to the scan chains over the area of the chip to reduce wire length back to the input/output test pins. The compressor and decompressor may be distributed in a 2-dimensional grid. The compressor may XOR each scan chain in two different directions such that a fault may be resolved back to a specific region of the IC.

Abstract: An electrical heater, to be powered from an automotive-type cigarette lighter socket, includes a heating element, a plug configured to be inserted into the cigarette lighter socket, and a pair of conductors permanently connecting the heating element to the plug. The plug has a flat substrate and a pair of conductors mounted on the substrate. An electrical plug, for a lighter socket of the kind having an inner wall of a predetermined diameter and a pair of electrical contacts, includes a flat assembly having a flat dielectric base having a width corresponding to the predetermined diameter, and a pair of flat conductors attached to the base for touching the pair of electrical contacts in the socket.
