The proposed fault- modeling strategy has been implemented to develop analog fault models representing the effect of spot defects in CMOS circuits. Results from an initial study of opamps are summarized and detailed results from onc example are included as an illustration of the fault- modeling process. 1 Introduction Application of analog components within large digital systems - a typical configuration in modern mixed analog/digital IC's - generates many new challenges in both design and testing areas (l), (2), (3), (4). EspccialIy difficult to solve are testing problems due to the observability limitations caused by the nature of the boundary between the digital and analog components of mixed IC's. Although there are many mixcd IC testing problems, this paper focuses on only one of them - a strategy of fault simulation. More specifically, this paper introduces a fault- modeling methodology which could be applied to capture the malfunctioning of analog components in mixed IC's. The goal of the reported research is to develop fault models that enable efficient simulation of the entire mixed IC by using a technique that is as close as possible to traditional digital circuit simulation techniques. Hence, this paper concentrates solely on the fault- modeling technique. It is organized in the following way. In Section 2, the general fault-modeling methodology developed for analog components of mixed IC's is introduced. In Section 3, an implementation of this methodology for CMOS technology is described in morc detail. Finally, in Section 4, an attempt to generalize obtained results is made in order to determine the practicality of the proposed fault-modeling methodology. This section also gives a list of problems to be solved in the subsequent research dealing with testing of mixcd analog/digital integrated circuits.","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.

This implies that rules are given for the design of the monitor, the required resistance measurements, the applied data processing and the data presentation. This method can be applied to design monitors for various applications. For example, the monitor can contain one or more layers and can be process or product-related.

The theoretical principles of the method are discussed and the effect is calculated analytically for a model arrangement. For more realistic measurement situations, the results of numerical calculations, showing the strength of the effect and its dependency of situational parameters, are presented. First experimental results are added. 1 MOTIVATION During the last years, the market share of mixed-signal designs could be observed to be continously increasing. This tendency led to the introduction of dedicated mixedsignal test systems. For prototype debugging of purely digital circuits, internal measurement tools like electron beam !esters (EBTs) have proved to be valuable and at the moment efforts are undertaken to enhance these tools also for application to mixed-signal circuils. The main task herewith is to improve the voltage resolution of the EBT by reducing system-inherent noise. Thus the measurement of analog voltage signals becomes available at an acceptable signal-to-noise ratio [Gar 871. However, information in analog circuitry is often carried by currents and therefore not accessible for measurement with an electron beam tester. On the other hand, the capability of measuring supply currents to chip internal function blocks would allow for some kind of chipinternal IDDQ technique also in digital circuits [Haw 891. But the task of current measurement on chip-internal wires has been ncglected so far. To date, no mechanism has been presented that allows contactless rno:iitoring and measurement of chip-internal currents using an electron beam technique. Neither the measuremenl of the voltage drop caused by the rcsistance of chip-internal wires nor the evaluation of the deflection of the primary beam due to the magnetic field around a current carrying wire (in the range of some pm/A) provides a practical access to chip-internal currents [He1 911. The following paper will describe a promising approach to such a technique, that exploits the interaction between the magnetic field around a current carrying wire and secondary electrons emitted from its surface. 2 PRINCIPLES The basic interaction between a current and a moving electron (e.g. secondary electron) is established by the magnetic field caused by this current. Therefore, the interaction process is described by Ampere's Law and the Lorentz force, aA at p = -e--eeV@+evx(ZZxAJ","PeriodicalId":272630,"journal":{"name":"1991, Proceedings.
