Testing and Simulation,Part II

In Part I, we looked at testing methodology for backplanes. In this feature, we will review simulation methodology.

Simulation for custom backplanes is becoming a more important issue in design and development. Bustronic has submitted a bid for simulations for the PICMG 2.17 subcommittee for StarFabric. We've also been working with the connector companies for information on their simulation studies. The scope of the work is to optimize the signal pinouts and study the effects of interference of nearby and adjacent signals. In today's switched fabric backplanes, one can perform 622Mbps LVDS (Low Voltage Diffferential Signaling) simulations in 2mm HM connectors or non-standard connectors. -More-

PICMG 2.16 Update (cPSB Backplane)

The PICMG 2.16 specification has been ratified. The spec is available to PICMG members and can be downloaded on the PICMG site. Bustronic/Elma have announced cPSB backplanes that meet the PICMG 2.16 final specification.

 

PICMG 2.17 Update (Starfabric)

The PICMG 2.17 subcommittee for StarFabric met on Sept. 6th in Boston. Over 65 companies have joined the subcommittee. Simulations was one of the key subjects that was discussed. Several companies, including Bustronic/Elma, submitted bids to do the simulation work. There was also a lot of discussion on connectors, from minor details like pin tail lengths and shrouds to larger issues like future revision high-speed connectors. Bustronic/Elma did a brief presentation on high-speed connectors like the ZD, Metral, and VHDM types from the major connector companies.

The technology is coming along quickly. So far, StarGen has released both switch chips, Agere announced their StarFabric-to-H.110 bridge, Bustronic developed a StarFabric backplane prototype, and Elma has created modeling for a prototype chassis.


Bustronic Expands VME64x Product Line

Bustronic now offers 7U VME64x backplanes in sizes ranging from 3-21 slots. The backplanes feature controlled impedance stripline design and comes with stiffeners to prevent backplane bowing.
 

7U CompactPCI Backplane Line Now Available

Designed for 1U and 2U low-profile horizontal chassis, the new 7U CompactPCI Backplane line features an ultra-thin design to maximize the slots in minimal space. The power bugs are located at the bottom of the backplane (in the extra 1U of backplane space). Also included in this area are fan tray headers and a special "thin profile" design for rear cable access. Slot sizes currently include 2-slot and 4-slot options.
