XMODEL is a collection of tools and libraries that can turn your favorite SystemVerilog simulator into a powerful analog/mixed-signal simulator. With XMODEL, you can verify the functionality and estimate the performance of various large-scale mixed-signal systems that require both high accuracy and fast speed, all on a single simulation platform, SystemVerilog.
XMODEL uses revolutionary, patent-pending algorithms to accurately express and quickly compute continuous-time analog waveforms on an event-driven logic simulator. Unlike other analog simulators that use a set of time-sampled points to describe a signal waveform, XMODEL uses a series of events each described by a mathematical, functional expression of the signal. This allows XMODEL to achieve virtually infinite precision without relying on a fine time step, while using only a small number of events. This trait is analogous to the vector fonts that always achieve the best image quality regardless of the display resolution while requiring only a small amount of data.
Furthermore, XMODEL computes these functional expressions for analog signals in a purely event-driven fashion, without involving any time-step integration or numerical iterations. These algorithms make XMODEL both fast and accurate, typically achieving 10~100x speed-up compared to Verilog-AMS or Real-Number Verilog for the same accuracy.
Scientific Analog, Inc is showcasing XMODEL and MODELZEN at this year’s Design Automation Conference (DAC). At Booth #1339, you can learn how XMODEL and MODELZEN can help you run fast and accurate analog/mixed-signal simulation in SystemVerilog with auto-generated models. Check our YouTube video to sneak-peak what we are exhibiting at DAC!
Greetings! We are happy to announce that a new major release of XMODEL is now ready for downloads. This release significantly improves the GUI interface aspects, such as the new XMODEL Testbench Editor, XWAVE Waveform Viewer and GLISTER Integration Toolkit with Cadence® Virtuoso®. Also, the performance and stability of the core […]

Scientific Analog, Inc. is a young start-up founded in Palo Alto, CA with a belief that analog design flows can be as systematic as the digital design flows. Today, most of the System-on-Chips (SoCs) embedded in computers, smart phones, and home appliances are largely digital circuits, but the small amount of analog circuits included in them often render the whole system impossible to verify and cause delay to market. Scientific Analog, Inc. developed XMODEL to address this problem and gaining increasing attention from many IC design companies worldwide.
