But that's not unusual. In 1997, for example, Jon Peddie Associates (JPA), a Tiburon, Calif., research company, found that NEC Corp.'s PCX2 chip performed better than 3Dfx Interactive Inc.'s Voodoo Graphics chipset. After the results were made public, JPA, in a statement published on its home page, said it was informed of a driver optimization installed by NEC that could be disabled by renaming the binary executable test. When that driver was turned off, the chip didn't perform as well as the first time. NEC and its partner, VideoLogic Ltd., however, stood behind the original set of benchmarks.

MARLBORO, Mass. – Moving to make better use of the World Wide Web for EDA product support and training, Viewlogic Systems Inc. this week has rolled out three new Web pages. The sites offer interactive training and instruction, a defect-tracking system and a visual diagnostic capability.

Viewlogic claims to be breaking new ground with its interactive training capability, which includes both training on specific Viewlogic tools and instruction in more general topics, such as signal integrity. The training, said vice president of customer services Jim Meikle, will include classroom instruction at specific times. Not only do you get screen shots, you can also hear the instructor live,” said Meikle. You can talk to other students, and talk to the instructor through voice or a chat window.”

Informational seminars in topics such as signal integrity, board verification and FPGA design will generally be offered free, while the tools training is priced from $100 per seminar.

Though Viewlogic claims that its interactive instruction goes beyond the offerings of other EDA vendors, two independent consulting firms, Bytek and Technically Speaking, also offer interactive Web-based EDA instruction.Online monitoring

A new site that supports Web-based call tracking lets users input their passwords and IDs, and monitor the progress of a bug report online.”They have complete access to the progress of the case, same as a support engineer would have,” said Meikle.

Another linked Web page lets Viewlogic support personnel visually track what's happening on a customer's screen. If there's a problem that cannot be resolved verbally, the customer can give permission for his screen to be monitored. He can then come to the site, download a small client and work online with a support engineer.

Visual online support will be integrated directly into Viewlogic's eProduct Designer series of tools, Meikle said.

MISSISSISAUGA, Ontario –Hitachi Ltd. continued to consolidate its North America operations, announcing today (8/23) that it will merge its Canadian electronics and chip subsidiaries into a single unit.

A fully open virtual switch would halt product differentiation in its tracks, said Tom Nolle, president of telecom market analysis firm Cimi Corp. (Voorhees, N.J.). Even those who advocate open software models say carriers may want to write their own software applications to keep a tight hold on security and stability features.

We want to make CPML simple enough to enable a third-party independent software market to develop,” Digital Telecommunications chief executive Richard Graves said of the Call Policy Markup Language. But we expect carrier-developed applications will emerge much faster.”

Chuck Harris, vice president of marketing at telco switch startup Tachion Networks Inc. (Eatontown, N.J.), said his company is a fan of CPML but that carriers will want to ensure that software developed by independent startups will not harm network stability.

An HTML-like approach to creating a programmable network is the latest concept to emerge for future switches. In a series of reports on New Generation Voice” issued in July and August, Cimi cites three alternatives to the true virtual switch.

Protocol-based systems such as MGCP allow flexible interfaces between circuit and packet systems, but they require the definition of a gateway controller, which may impede the creation of embedded systems that can handle multiple switching and routing tasks in next-generation networks. In that model, the switch becomes little more than a rules engine, shuttling all intelligent processing of packets and time-division multiplexed channels to the gateway controller. The gateway could introduce a choke point of delay into the network, unless the definition of open switch primitives could speed the executive of controller-based instructions.
