Abstract: A system for testing large scale integrated circuits. The circuitry in an integrated package such as a card, module or a semiconductor chip is viewed as a partially functional logic unit. This circuitry is complemented with off-package logic to allow the combination to act as a complete functional logic unit to which functional test patterns may be applied. The complementary logic is preferably simulated in the memory of a computer-controlled tester.

Abstract: A high speed, high performance integrated circuit packaging structure that may be used for emulating wafer scale integration structures. The preferred embodiment comprises an interposer (9) having a base substrate having alternating insulation and conductive layers thereon, wherein a plurality of the conductive layers are wiring means which are adapted for maintaining an extremely low noise level in the package. The low noise level and low resistance and capacitance of the wiring means allows a plurality of discrete semiconductor segments (32) to be mounted on and interconnected by the integrated circuit package with a significantly reduced number of drivers and receivers than required by Rent's Rule. Each integrated circuit structure (9) of the present invention emulates a large chip or wafer scale integration structure in performance without having to yield the large chip or wafer, and without redundancy schemes. A plurality of these integrated circuit packaging structures (9) are combined by decals (29, 31) to form a central processing unit (1) of a computer or a portion thereof. In an alternate preferred embodiment, the base substrate of the interposer is made of silicon and any required drivers are formed therein, thus substantially eliminating the need for any drivers on each of the discrete semiconductor segments (32).

Abstract: A method and apparatus for testing large or very large scale integrated circuit packages is described. The testing equipment required for testing such packages is assumed to lack the number of channels necessary to connect one channel to each input/output of the unit under test. A computer program classifies all input terminals in a plurality of categories, each of which corresponds to particular circuit type and electric network configuration connected to that pin. A unique set of DC levels is defined prior to testing for each class of inputs. These levels are supplied by the tester channels, each of which drives a multitude of input pins that belong to the same category. The assignment of tester channels in the aforementioned arrangement is implemented by means of multiplexers that select for each pin the appropriate set of DC levels, and a memory buffer contained in the tester, with the DC test patterns stored wherein. The bit configuration of each pattern controls plural switching devices that deliver the appropriate DC levels to the terminals of the unit.
