Latest version of XMachina: [1190515] download New features: Common ground architecture option in the design task setup window. Check it to get circuits designed with common ground, something like: Design time manager. For example, to get 4 designs until the same time next day set it this way: so XMachina will spent 6 hours on each design. Needless to say the longer design time the better results to be expected, however before starting long designs it’s recommended to execute few test 5 to 10 min designs just to make sure that there are no issues in the design task settings. It’s also easy to setup a test run with the time manager feature, for instance: XMachina can design in the background. No special settings are needed, for example while XMachina is working on design nr 3 of 4 you can analyze or edit finished designs nr 1 and 2. The design process nr 3 is being continued in the background (then nr 4).
