Our signal integrity analysis and simulation services ensure efficient cost-effective design solutions that work superbly the first time, every time. And we continue to expand our technical resources with new high-speed measurement technology, interconnect model extraction, and software to support measurement-driven design. The simulations predict the characteristics of a custom design and eliminate “trial and error,” resulting in faster turnaround and guaranteeing that our products meet or exceed your specifications.
High-speed backplanes are by nature more sophisticated and delicate. At higher clock speeds, the PCB demands cleaner signal transmission without compromising the stability of the system. This is where Signal Integrity engineering comes into play. Simply put, signal integrity studies the design of highspeed
circuits that can accommodate cleaner signals passing through them. Elma's creative routing techniques reduce layer counts, preventing long via stubs that hamper signal continuity. To optimize VPX backplane performance, we often use low-loss dielectric laminate materials like FR408 or Nelco 4000-13SI for our high-speed backplanes.
ELMA can perform simulations for any backplane and to include also the transmitter and receiver cards geometries and the driver specified by the customer. Also, ELMA simulations can suggest the best de-emphasis level for drivers and other possible equalization methods. For each product, ELMA optimizes the channels so the backplane induced losses to be minimum and to suit the custom or standard specifications requirements. ELMA simulations have been used over the years to gain the know-how necessary to face higher and higher data-rates. This simulation tools know-how can also be used for each project at the customer request.
