The Qucs file based voltage source example does not load (because of changes in the QucsStudio format), and even when you fix it so it can load, QucsStudio definitely reduces to understand the DA and CVS files. To generate a waveform analogous to an eye diagram, we can apply infinite persistence to various analog signals a well as to quasi-digital signals such as square wave and pulse as synthesized by an arbitrary frequency generator (AFG). oscillators, peak detectors, periodic steady-state analysis etc. I've just started with it, and it seems too good to be true. The following files contain circuits that demonstrate the functionality of simulator and GUI. Light from points beyond the far-point would have less divergence at this eye and be foused in front of the retina. With eye diagrams you can see signal quality with one display, you can diagnose problems, such as attenuation, noise, jitter, and dispersion that arise or characterize specific parts of the system.
