The new release of HyperLynx from Mentor Graphics supports advanced 3D channel and trace modeling, improved DDR signoff verification, and accelerated simulation performance up to 5X faster. HyperLynx helps in analyzing potential high-speed design issues arising from signal integrity, power integrity, and electromagnetic interference (EMI) performance.
“In applications above 10 Gbps, insertion loss will often exceed -12 dB at the Nyquist and eyes will be completely closed. Successful designs require getting everything in the design right and building confidence in the design early in the design cycle with accurate simulations,” stated Eric Bogatin, signal integrity evangelist, Bogatin Enterprises, a wholly owned subsidiary of Teledyne-LeCroy. “The accuracy of the latest release of Mentor Graphics HyperLynx was recently validated with a 12.5 Gbps backplane design from Molex that included causal material models, copper surface texture contributions, via models, mode conversion and reflections from integrated S-parameter models of connectors.”
The new HyperLynx product decreases the amount of channel modeling that requires 3D analysis with advanced area fill-aware 2.5D planar trace extraction. When this advanced feature is enabled, the system will model variations in signal trace impedance or delays due to non-ideal planes and references (complex area fills with voids and cuts). The resulting impedance variation effects are included during time domain simulation and s-parameter model extraction.
Other capabilities found in this new HyperLynx release includes:
Pre-layout DDRx signal integrity and comprehensive cycle-based timing simulation during parametric sweeps. The HyperLynx DDRx wizard supports DDR3L and DDR3U supply levels by incorporating the required derating tables, timing models, and voltage levels, plus test-load compensation of signal launch delays using the DDRx wizard.
Batch support of s-parameter models from the post-route environment; interconnect modeling with accurate wideband dielectric models and surface roughness
Advanced meshing for DC drop analysis to review accuracy of narrow slivers of metals within complex designs
Accelerated simulation flow of IBIS AMI models in statistical mode with LTI equalization algorithms; this feature is based on peak distortion analysis techniques and statistical algorithms that process impulse response of the channel directly for eye diagram generation to quickly produce results for buffers with LTI equalization schemes down to very low BER
Improvements to the advanced waveform viewer and processor, a graphical environment for displaying and analyzing large sets of simulation results that has many advanced measurements for complex waveform processing using a rich set of calculator functions. Improvements include an interactive simulation GUI that automatically plots centered eye diagrams.
Availability: The new HyperLynx release will ship in March 2013
