While the new technology has many other potential applications, ST says that it was developed specifically to meet the needs of mobile phone manufacturers. The cellular handheld market is intensely competitive and there is great pressure to reduce the cost of the components,” Ferla says.

The filing said the deal is expected to close in the first half of calendar 2002, subject to regulatory approvals, satisfactory completion of due diligence by Micron and the negotiation and execution of definitive documentation.

The purchase price is toward the lower end of the $250 million to $400 million figure that was disclosed by sources close to the negotiations when the deal was announced on December 18.

The cost to Micron of acquiring the leading edge 0.17-micron processing fab is roughly a quarter of the $1 billion to $1.2 billion cost of building a similar new fab from scratch.

SAN MATEO, Calif. — Plato Design Systems Inc. has integrated an RC extraction engine and added other enhancements to a new version of its IC router.

Joe Xi, vice president of marketing for Plato Design, said the company's NanoRoute-SI (for signal integrity”) does concurrent, global and detail routing; online 3-D-accuracy RC extraction; timing and noise analysis; buffer insertion; gate sizing; and logic restructuring.

Coupling capacitance is going to pose the next big problem for high-performance system-on-chip designs,” said Xi. The 0.25-micron process broke wire load models and required physical-synthesis tools that use length-based RC models. We believe that at 0.13 micron and below, most of the capacitance is coming from coupling capacitance, which is almost impossible to predict with length-based RC models. Coupling capacitance really only reveals itself at the detailed routing stage.”

Xi said the company predicts that at 0.1 micron, inductance is also going to become a huge issue, and length-based RC models will be ineffective, fueling a need for routers to run concurrently with extraction.

For the new offering, Xi said, Plato built a quick 3-D extraction engine from scratch that does full-chip coupling-capacitance extraction only on the interconnect, not the device. The routing and extraction engines access information from the same database. That, according to Xi, means router run-times are not slowed significantly: The speed penalty is 5 percent to 10 percent slower performance than for typical NanoRoute routing, he said.

In the last five years, fuel cell power trains have dropped from being 1,000 times as expensive as an internal combustion engine to about 10 times as expensive,” noted Cole of the Center for Automotive Research. But they've still got to come down to be roughly comparable to an [internal-combustion] engine in cost. They have a long way to go.”

By-wire technologies, which include steer-by-wire, brake-by-wire, throttle-by-wire and suspension-by-wire, are further along than fuel cells, but still years away from large-scale production. Because such systems lack the inherent redundancies of hydraulic-based technologies, engineers are still hard at work on the development of time-triggered, safety-critical data bus architectures that would ensure safe message passing.

Such technologies, however, are the key enablers for GM's new, modular concept. That's why GM has accelerated its efforts with suppliers in both arenas, its engineers said. The giant automaker has formed an alliance with Hydrogenics Corp., a fuel cell technology company that makes proton-exchange membranes that serve as a key component of the electrochemical reaction in fuel cells. It has also partnered with Quantum Technologies Inc. to develop hydrogen storage devices, which will be critical if 5,000-psi gaseous hydrogen is employed as a fuel.

In addition, GM is teaming with Giner Inc. on hydrogen generation for refueling systems, General Hydrogen on infrastructure issues and Suzuki Motor Corp. on the entire fuel cell system.

For further development of by-wire technologies, GM is also working with SKF USA Inc. (Norristown, Pa.). SKF, which has produced fly-by-wire systems for Airbus for more than a decade, last year introduced the FILO by-wire car at the Geneva Motor Show.
