Cover: A rendition of the multiple views of time-correlated data provided by the HP 16505A prototype analyzer
Reducing Time to Insight in Digital System Integration. Digital design teams are facing exponentially growing complexities and need processes and tools that reduce the time needed to gain insight into difficult system integration problems. This article describes modern digital systems in terms of the problems they create in the system integration phase. The debug cycle is described with special emphasis on the “insight loop”, the most time-consuming phase of system integration. A case study from an HP workstation design effort is used to illustrate the principles. A new digital analysis tool, the HP 16505A prototype analyzer, is introduced as a means of solving these vexing problems more quickly by reducing time to insight, by Patrick J. Byrne, pg 6-14
Prototype Analyzer Architecture. The HP 16505A architecture allows multiple concurrent views of acquired logic analysis data. Markers on all views are correlated. The user only needs to place the marker on one view and the markers on the other views automatically relocate. Thus a stack anomaly in one view can be immediately correlated with the software routine causing the violation, by Jeffrey E. Roeca, pg 15-21
Determining a Best-Fit Measurement Server Implementation for Digital Design Team Solutions. Prototype analyzer customers wanted fast throughput, quick answers, a turnkey solution, an affordable base system price, connection to diverse open-systems networks and platforms, and interfaces to a wide variety of tools. An encapsulated measurement server architecture based on a dedicated workstation and a SCSI II interface best fit the requirements, by Gregory J. Peters, pg 22-29. 16505A.
A Normalized Data Library for Prototype Analysis. The goal was that each analysis and display tool to be included in the prototype analyzer should be designed and written only once. Therefore, the data library is designed to normalize the variety of basic logic analyzer data types and the variety of postacquisition data types generated by various analysis tools and to present this data to other analysis and display tools in a standard format, by Mark P. Schnaible, pg 30-37. 16505A.

The Evolutionary Development Model for Software. The traditional waterfall life cycle has been the mainstay for software developers for many years. For software products that do not change very much once they are specified, the waterfall model is still viable. However, for software products that have their feature sets redefined during development because of user feedback and other factors, the traditional waterfall model is no longer appropriate, by Barbara A. Zimmer, Elaine L. May, pg 39-45. EVO, Evolutionary Development.
The Software Initiative Program, pg 42
HP Domain Analysis: Producing Useful Models for Reusable Software. Early software reuse efforts focused on libraries of general-purpose routines or functions.

Recent software reuse efforts have shown that architecture-based, domain-specific reuse can yield greater quality and productivity improvements, by Patricia Collins Cornwell, pg 46-55
Reuse Roles: Producers, Supporters, and Utilizers, pg 50
A Model for Platform Development. For many software and firmware products today, creating the entire architecture and design and all the software modules from the ground up is no longer feasible, especially from the point of view of product quality, ease of implementation and short product development schedules. Therefore, the trend is to create new product versions by intentionally reusing the architecture, design, and code from an established software platform, by Emil Jandourek, pg 56-71
A Decision Support System for Integrated Circuit Package Selection. The package provides signal and power distribution, heat dissipation, and environmental protection for an integrated circuit (IC). The process of selecting a package is complicated by the large number of packaging alternatives with overlapping capabilities. To handle these difficulties, a decision support system was developed. The Package Selection Systems (PASS) combines expert system tools and multiple-attribute decision making techniques. The expert system provides a list of technically feasible alternatives. The multiple-attribute decision making modules are used to rank the alternatives based on nontechnical criteria, by Craig J. Tanner, pg 72-79. MLM, Manufacturingless Manufacturers, MADM.
Cycle Time Improvement for Fuji IP2 Pick-and-Place Machines. Some of the major enhancements are eliminating head contention, reducing or eliminating nozzle changes, supporting user-defined nozzles, supporting large nozzles for holders 2 and 3, and being able to define multiple part data for a given part number. The cycle time improvement exceeds the original goal of 5%, and the result at one surface mount center was more than 16% over hand-created and optimized recipes. The solution helps both the high-volume and the high-mix centers, by Fereydoon Safai, pg 80-83
Reducing Setup Time for Printed Circuit Assembly. In 1994, HP’s Man-Link recipe generation system was enhanced to reduce the time required for setting up pick-and-place machines. This was done by ordering the products to exploit the commonality of parts among them and by creating sequences of setups that differ as little as possible from one another. This paper documents the issues and trade-offs and discusses the potential benefits, by Richard C. Palm, Jr., pg 84-90
Low-Temperature Solders. The application of low-temperature solders in surface mount assembly processes for products that do not experience harsh temperature environments is technically feasible. One single alloy may not be appropriate as a universal solutions, by Hubert A. Vander Plas, Zequn Mei, Helen A. Holder, pg 91-98. EADC, Electronic Assembly Development Center.
Assessment of Low-Temperature Fluxes. The subject of this paper is the evaluation of the wetting balance as a technique for studying the flux activity of newly developed low-temperature solder paste fluxes. The most effective configuration of the wetting balance was the standard configuration with only one change: the PbSn eutectic solder was replaced with a eutectic solder alloy with a melting point of 58°C. Since 58°C is significantly less than the proposed activation temperatures of the solder fluxes, wetting curves as a function of temperature could be studied for each of the fluxes. The resulting data was used to rank the fluxes in terms of the activation requirement, by Helen Holder, Zequn Mei, Russell B. Cinque, Hubert A. Vander Plas, pg 99-103

Radially Staggered Bonding Technology. This new approach to fine-pitch integrated circuit bonding entails a new configuration of bonding pads on the die, dual-loop wire bonding, and a new leadframe design that minimizes wire lengths.
