The integrated circuit revolution has impacted virtually all fields of engineering. The main driving force behind this revolution is Complementary Metal-Oxide Semiconductor (CMOS) transistor technology. As CMOS integrated circuit “chips” have come to dominate analog and digital electronics, introductory electronics courses in Electrical and Computer Engineering programs have evolved to place gr...

The application of COS/MOS integrated circuits in the construction of a three-valued positional control system is presented. A unit-distance ternary code and the design of a ternary encoder are given. A ternary code converter able to translate this unit-distance code to the signed ternary code is described. A ternary threshold level detector is required to convert a noisy, slowly-changing, anal...

Due to the globalization of the integrated circuit manufacturing industry, hardware Trojans constitutes an increasingly probable threat to both military and commercial applications. The Trojans being stealthy in nature, the Trojan hardware is hard to be triggered under random patterns. In this paper, we propose practical test patterns generation technique based on rare logic conditions at inter...

Hardware Description Languages (HDL) like VHDL are widely used to design and simulate with programmable logic devices. Simulation of very large scale integrated digital systems (VLSI) is of great importance as it assures system correctness and maximizes system performance ([4], [5], [9]). The utilization of parallel simulation introduces the problem of how to partition the logic gates and syste...

As a step toward automatic circuit understanding, we present a new method for analyzing circuit structures. We view circuits as sentences, and their elements as words. The electrical behavior and functions are the meaning of the sentences. Circuit structures are defined by a logic grammar called DCSG. A set of grammar rules, when converted into Prolog clauses, forms a logic program which perfor...

An all-optical 2-to-4 decoder unit with the assist of terahertz optical asymmetric demultiplexer (TOAD) is presented. The all-optical 2-to-4 decoder with a set of all-optical switches is designed which can be used to achieve a high-speed central processor unit using optical hardware. The unique output lines can be used for all-optical header processing. We attempt to develop an integrated all-o...

A boundary-scan logic design method that depends only on level-sensitive scan design (LSSD) principles has been developed for IBM CMOS application-specific integrated circuit (ASIC) products. This technique permits comprehensive testing of LSSD ASlCs with high signal input/output (I/O) pin counts, using relatively inexpensive reduced-pin-count automatic test equipment (ATE). This paper describe...

Reversible Logic is an emerging technology; it has hellocious applications in various fields. Reversible logic implementation reduces loss of entropy because of bit manipulations. Conservative reversible logic gate obeys reversible logic rules and also satisfies the property that there is equal number of 1s in the outputs as in the inputs. In this work, modified design of SCRL (Super Conservati...

This paper deals with the test of an integrated on-line multiplier suitable for very large numbers. Due to the serial structure of the circuit, the controlability and observability of the different elements are very low. In particular, an embedded sequential Iterative Logic Array cannot be accessed directly and has no primary outputs. Thus some modifications of the circuit are made to enhance t...
