Prevas develops complex electronics design  for Dolphin Interconnect Solutions

The Norwegian electronics industry is focused on specially developed "complex" designs. A new development contract for high-speed data communications, which will be deployed in the next-generation of interconnect solutions, is proof that Prevas is continuing to maintain its position among the leaders in the design market.

In February 2011, Prevas' company in Norway won an order from a significant customer, Dolphin Interconnect Solutions AS. The product that will be developed is a high-speed data switch for interconnecting computers over cable. The first prototypes will be finished in June, allowing considerably faster data streams than those possible to date with corresponding solutions. The products are expected to be delivered to the market during the second half of 2011.

Prevas, in collaboration with the customer, has developed the system specification for the product and is also responsible for the electronic design, schematics and circuit card layout. The design is special in that it involves as many as 128 high-speed balanced data bus conductors embedded on the circuit card, which will transmit as much as 5 gigabits of data per second before being distributed over copper cabling.

To succeed in designing such a product, Prevas has both the necessary software tools and a number of employed physicists with industry experience — resources that are considered vital to manage such a project. The physicists are required to design in the necessary electromagnetic design thinking from the very start. Design work of this type would be impossible without high-class tools to simulate the design of the signal, a scenario analysis and circuit card simulation, which is why Prevas has acquired a number of tools for designing layouts and simulating signal integrity. Prevas also has the measurement equipment for analyzing high-speed signals.

"This is Prevas' first major in-house-project in Norway. With this project, we aim to consolidate our position as a major player in the sector for complex electronics design and offer services to customers that are planning to procure next-generation technology," says Eivind Eriksen at Prevas AS.

The product, which operates with a central packet switch from Integrated Device Technology, will be capable of switching data between 8 ports based on PCI Express generation 2. Each port has 8 channels, each for 5 Gbps. The design can also be used with the third generation of the packet switch, also for 8 Gbps, which is expected to be available before the summer of 2011. After being switched on the circuit card, the signals are transmitted over copper cabling that can be up to 7 meters long. Active, fiber-optic cables up to 300 meters in length can also be used.

Connected computers can operate efficiently together in processor clusters in super computer architectures, but at moderate cost. This is possible with Dolphin's SuperSockets communications software. The new product will transfer data at approximately twice the speed as the product currently offered by the closest competitor in the market. Latency in the architecture is only 1/10 the latency in 10 Gbps Ethernet. The bandwidth for second-generation products is about four times as high as for 10 Gbps Ethernet.
