The J-QIE web-based simulator
Please note: the first time you press INITIALIZE it can take up to a few minutes for the initialization to complete. Your browser may show a pop-up telling you the window is not responding, but let it continue. Also, after the initialization is complete (you will see some small bars in the display area), when you press RUN for the first time, it will take maybe 20-30 seconds to start. After that, INITIALIZE and RUN will work very quickly, so you can test different scenarios.
