ModelRisk is a Monte Carlo simulation Excel add-in that allows the user to include uncertainty in their spreadsheet models. ModelRisk has been the innovation leader in the marketplace since 2009, being the first to introduce many technical Monte Carlo method features that make risk models easier to build, easier to audit and test, and more precisely match the problems you face. A ModelRisk user replaces uncertain values within their Excel model with special ModelRisk quantitative probability distribution functions that describe the uncertainty about those values. ModelRisk then uses Monte Carlo simulation to automatically generate thousands of possible scenarios. In the same way that Excel is used for many different types of analysis, ModelRisk is used to assess the uncertainty in the numbers produced by the Excel model. Users have performed risks analyses with ModelRisk in a vast range of fields.

PrimeSim HSPICE circuit simulator is the industry's "gold standard" for accurate circuit simulation and offers foundry-certified MOS device models with state-of-the-art simulation and analysis algorithms. With over 25 years of successful design tape outs, HSPICE is the industry's most trusted and comprehensive circuit simulator. For on-chip simulation, analog designs, RF design, custom digital design, standard cell design and characterization, memory design and characterization, and device model development. For off-chip signal integrity simulation, silicon-to-package-to-board-to-backplane analysis and simulation. HSPICE is a key part of the Synopsys analog/mixed-signal (AMS) verification suite, a solution built to address the most critical issues in AMS verification.
