Simulation Accelerator Toolbox for MATLAB
This toolbox presents an abstraction layer that can be put in front of our Subset Simulation Toolbox to simplify and speed up subset simulations with Simulink models. In short, it contains a custom code generation and compilation process that produces a binary simulation target that is optimised for speed in the context of subset simulation.
The details of the inner workings and architecture are captured in the user manual and publication linked above. In short summary, it might give you 5–15⨉ faster simulation results when you iterate Monte Carlo samples than what you are able to achieve using the standard simulation tools.
Features
Simulation target optimised for speed
Contains our CompiledScenario class that produces a binary simulation target that is optimised for speed when used together with our Subset Simulation toolbox.
Easy setup of subset simulation studies
Define a simulation Scenario, a list of Parameter objects and a failure Metric, then join them in a subset simulation Study that is ready to start.
Iterative build artifact generation
Our custom code generation procedure uses an iterative Makefile-like approach. To regenerate certain artifacts, just delete them and start the process again.
Support for many official toolbox features
Use embedded or external test harnesses, load scenario configuration from Test Manager files, automatically discretise models, and automatically select the best call signature of sim() and parsim(). If you are familiar with the official APIs, you should be able to get started quickly.
Case Studies
Speeding up simulation of an eVTOL
In this study (DOI link below), the authors compared simulation times for an eVTOL simulation model of comparative modelling complexity as would be needed for requirement verification. The code generation toolchain available in this toolbox (in the table named “proposed”) had a comparable setup time as the other simulation modes, but execution time was only a fraction, leading to a simulation speedup of 73⨉ in total, or 5⨉ above the fastest built-in simulation mode (rapid accelerator).
