Engineers designing servers, storage devices, multimedia PCs, entertainment systems, and telecom systems have driven an industry trend to replace legacy shared parallel buses with high-speed point-to-point serial buses. Standard interfaces like XAUI, XFI, Serial ATA, PCI Express, HDMI, and FB-DIMM have emerged to provide greater throughput using serial signaling rates of 2.5 to 10 Gb/s. Trends toward point-to-point serial interconnects provide numerous and distinct system implementation advantages. While these advantages compel the standardization and rapid adoption of serial links, it also has attendant challenges for system and board designers. Reliable signal transmission across a host board or between daughter cards on a backplane at GHz speeds compels adoption of new strategies and tools. This reference flow document (download above) outlines a reference design flow/methods that leverage Ansoft's expertise in advanced circuit simulation and electromagnetic extraction tools to reliably characterize and design complex serial channels so that engineers can overcome the design challenges for high-speed serial interconnects. |

Nexxim®
Nexxim® is an advanced, frequency- and time-domain circuit simulator for engineers designing the next generation of high- performance DigitalRF CMOS ICs, GaAs/SiGe RFICs, SIP/SOC packages, power delivery systems and gigabit computer and communication backplanes. Dynamic, parameterized co-simulation with HFSS™ and Ansoft Designer® enables Nexxim to combine transistor-level detail for complex and highly nonlinear circuits with full-wave S-parameter models of the interconnect to provide the most accurate simulation capability for signal-integrity analysis and RF design.
Ansoft Designer®
Ansoft Designer® provides an integrated schematic and design management front-end for complex analog, RF and mixed-signal applications. By leveraging advanced electromagnetic field simulators dynamically linked to powerful circuit and system simulation, Ansoft Designer enables engineers to design, optimize, and validate component, circuit, and system performance long before building a prototype in hardware.
HFSS™
HFSS™ is the industry-standard software for S-parameter, Full-Wave SPICE™ extraction, and 3D electromagnetic field simulation of high-frequency and high-speed components. Engineers rely on the accuracy, capacity, and performance of HFSS to design on-chip embedded passives, IC packages, PCB interconnects, antennas, RF/microwave components, and biomedical devices.
