Debug Mode and Fast Mode
20-sim can operate in two modes: Debug Mode and Fast Mode. This
is indicated by the Mode button in the toolbar. You can quickly
change between these modes by clicking on the Mode Button. In
Debug Mode all possible checks will to performed and warnings
will be generated for possible model errors. Always start modeling
in Debug mode!
In Fast mode a built-in runtime compiler is used that instantly translates
the simulation model into platform specific 32-bit machine code.
The result is a dramatic increase of simulation speed. Often 20-sim
machine code runs faster than the equivalent compiled C-code.
Compiling the machine code, even with large models, is done while
you start up the Simulator. The compiler is an internal part of
the 20-sim software, so no external compiler or program is required!
Simulation Algorithms
20-sim contains powerful simulation algorithms for solving ordinary
differential equations (ODE) and differential algebraic equations
(DAE). It has a variety of numerical integration methods: one-step,
multi-step and multi-order.
Discrete-time models
20-sim will automatically detect discrete-time loops in a model
and assign each independent loop a separate sample rate. Discrete
signals are shown in the Editor in green. Discrete-time parts
are activated by time events so that mixed continuous-time and
discrete-time models are handled correctly.
Events
20-sim can also handle state events based on zero-crossing algorithms.
This results in a fast and accurate event detection and localization.
