Industry View -- Exclusive to Electronic Design UPDATE ********************** Automation Turns Nightly Builds Into Espresso Break Builds By John Graham-Cummnning, Cofounder and Chief Scientist, Electric Cloud No self-respecting engineering team works without source-code control or a bug tracker, and almost every quality-assurance (QA) team installs expensive test automation tools. Yet build teams use 20-year-old tools like Make and cobbled-together Perl scripts to run the critical stage of actually building the final product. It's time that changed. In fact, time's up for creaky homegrown build systems. As engineers employ agile development methods requiring constant integration, and development schedules get squeezed by pushes for ever faster time-to-market, the hours-long nightly build is an anachronism...

These ADCs deliver the highest performance at the lowest power and allow you to change resolution and speed with ease. And to make designing with ADCs even easier, National and Arrow offer an online seminar, an online eBook and the WEBENCH Signal-path designer tool-all on http://news.electronicdesign.com/t?ctl=1C3E2:484C79 **************************************************************** *******************Live on ElecDesign.com*********************** Free Web Seminar: RoHS -- The Manager's Role, Part 2 December 21, 2005 at 2:00 pm ET Join us for our second Web seminar that looks at the manager's role in the transition to compliance with the European Union's Restrictions on Hazardous Substances (RoHS). We will identify and explore the decisions that industry managers have to make. Register today! http://news.electronicdesign.com/t?ctl=1C3D2:484C79 Free eBook: A Black-Box Approach To ADCs This eBook provides a black-box approach to the traditional analog-to-digital coverter (ADC) tutorial. It concentrates on the common characteristics of all ADCs and what they imply for the system-level designer. The second chapter is now available. Download the first two chapters today! http://news.electronicdesign.com/t?ctl=1C3DA:484C79 **************************************************************** ********************** 2. Focus On Test & Measurement ********************** ***Control Instruments Anywhere Through Ethernet-To-GPIB Interface The Model 8065 Ethernet-to-GPIB controller provides access to multiple general-purpose interface-bus (GPIB) instruments from any computer with a network-interface-card interface or connection to any TCP-IP network. With this device, users can share test instruments from anywhere in the world using a PC connected to a company network or the Internet. The 8065 complies with the VXI-11.2 communication standard for LAN-to-GPIB servers and with the VXI-11.3 standard for LAN-controllable instruments. The VXI-11 Service can be accessed from National Instruments LabView, Agilent Vee, Visual Basic, and C application programs that call for a VXI-compliant VISA layer. The 8065 comes with a VXI-11 Keyboard utility program that lets users with WIN32 computers control GPIB devices without having to write a program. Also, an included configuration utility lets users set the IP address, GPIB address, interface name, and other settings. It can handle up to 15 VXI-11 links. The Model 8065 costs $695 each in quantities of one to four units, with delivery in four to five weeks. Versions that comply with the European Union's Restrictions on Hazardous Substances (RoHS) will be delivered in March 2006.

News -- From The Editors ********************** ***Seminars Bring Power Know-How Close To Home A series of power seminars will soon arrive at an American or European city near you. The seminars will present fresh approaches to switching regulator topologies and implementations, practical application issues for switch-mode power supplies, and help with understanding today's power MOSFETs. Conducted by power experts from Fairchild Semiconductor's Global Power Resource design centers, the seminars will cover the latest design techniques, tips, and tools for optimizing system power. The seminars kick off on January 30, 2006 in Stockholm and conclude on May 17, 2006 in Moscow. In between are stops in locales such as Stuttgart, Germany (February 8); Huntsville, Alabama (March 15); Dallas, Texas (April 6); San Jose, California (April 25); Phoenix, Arizona (April 27); and Tel Aviv, Israel (May 11). Visit the company's Web site for a complete list of seminar dates and venues. Fairchild Semiconductor ==> http://news.electronicdesign.com/t?ctl=1C3DD:484C79 ***Interconnect Technology Weaves An On-Chip Web One of the most critical issues for system-on-a-chip (SoC) designers is the interconnections between the many IP blocks that comprise the device. Traditional on-chip bus architectures have proved to be a design and performance bottleneck. Now, a network-on-chip technology promises to give designers a leg up on interconnect issues by making possible the proper price/performance tradeoffs. STMicroelectronics' ST Network on Chip (STNoC) technology replaces the traditional circuit-switched bus with a packet-based paradigm that incorporates a layered protocol stack analogous to a very simplified networking scheme. IP blocks such as processor cores, cache memories, connectivity I/O functions, or audio/video codecs are simply plucked from a library, added to the SoC design, and empowered to communicate with each other by means of a high-speed, low-power, packet-based communications protocol. ST's Spidergon topology arranges all of the SoC's IP blocks in a ring. Each IP block is connected to its clockwise and its counter-clockwise neighbor as in a simple polygonal ring topology. However, each IP block also is connected directly to its diagonal counterpart in the network. This allows the routing algorithm to minimize the number of nodes that a data packet has to traverse before reaching its destination.

The TAJ "R" capacitors offer height options of 1.2, 1.5, and 2.0 mm, which equal the heights of standard IC packages after mounting. They'll find myriad applications in computer power supplies, disk drives, cellular handsets, and PCMCIA cards. The capacitors come in a range of values from 0.1 to 22 microF with a capacitance tolerance of +/-10 percent to +/-20 percent. Their operating temperature ranges from -55 deg.C to 125 deg.C. They're available on standard 7- or 13-in. reels in quantities of 500 to 10,000. Pricing is around $0.21 each in volume quantities.
