This option allows the export of the model of the entire system represented in the SYSTEM ARCHITECT schematic editor, to a 3rd party external system simulator, in the form of a macro-model. The macro-model embeds its equation solver, which allows keeping the same precision in the target system simulator, even if the latter is not natively equipped with an equation solver as powerful as Vision in ‘data-flow’ mode, for example, to take into account the phenomena of mismatches between circuits or memory effects.
In that matter, Vision is indeed a unique tool, which allows unifying a global design process, from measurement or simulation at the circuit level to system simulation. The number of exports is unlimited, but only available for licences under maintenance program.
