QuickWave version 6.0 rev. 3 DEMO is free and fully operational in terms of the interface, but it does not enable simulating your own examples. It does allow unrestricted creation of any projects in QW-Editor, but then such projects cannot be saved or exported to QW-Simulator. QW-Simulator in the DEMO version functions in the same way as in the full-power version, but only on predefined examples, which include all examples described in QW-3D manual, also available in the DEMO installation. The user can use the software without hardware dongle and time restrictions.
