Tools for high speed digital interface analysis on printed circuit boards The Quantum-SI™ products are used to perform high-speed digital interface analysis between components that are located on one or more printed circuit board (PCB) designs. Specifically, Quantum-SI solutions may be used to: Quickly explore and analyze alternate topologies or termination schemes for high-speed parallel and serial interface designs. Perform exhaustive pre-layout solution space analysis over the full range of environmental conditions to determine the PCB layout constraints. During the pre-layout process, Quantum-SI is used to analyze: Waveform quality and eye diagram characteristics The effects of simultaneous switching outputs and crosstalk coupling Setup/hold timing margins for synchronous and source-synchronous interfaces Perform post-layout verification to validate that the implementation meets system waveform quality, timing and noise margin requirements. During the post-layout process Quantum-SI is used to verify: Waveform quality for all high-speed digital interfaces Board crosstalk limits are met (single and multi-board configurations) System-level noise and timing margins are met In addition, Quantum-SI includes the following add-on options that enable engineers to: Convert single-ended and differential HSPICE I/O models to IBIS models. Quantum-SI provides a highly automated process to rapidly convert large numbers of HSPICE models to high-quality IBIS models and to correlate the generated models to the originals. Fully analyze I/O buffers with their associated system-level interconnects to drive critical I/O selection, decoupling and timing requirements into the ASIC/IC/FPGA component development process.
