Deeds: Digital Electronics Education and Design Suite is a set of educational tools for Digital Electronics. It covers various areas of digital electronics, like combinational logic networks, sequential logic networks, custom circuit blocks design, micro-computer programming, and more. The program helps students learn to design (and test) electronic systems, test digital systems on FPGA boards, and more.
v1.7 [Nov 26, 2012]
· A new “Push-button” input component has been added. It is useful, during interactive animation, to represent not only a real push-button device, but also to simulate pulse-shaped input command signals (i.e.: system reset).
· User can define, as a property of the component, if the button is “high” or “low” when pressed. The push-button is pressed with a mouse click; it is depressed when the mouse button is released. In the timing diagram window, the new push-button input track is defined as a usual switch input track.
· With the introduction of the new component, Switch and Push-button icons have been changed to highlight the differences between the two input components (in the main menu, in the component bin, in the timing diagram window and in the FPGA assignment window).
· Internal file version has changed (to 1.023), so files saved with the current Deeds version could not be opened in previous version. However, as usual, backward compatibility is maintained: current version can read all the previous version files.
· Bug fix: “demultiplexer” type components label have been corrected as “Dex 1 -> 2”, “Dex 1 -> 4”, “Dex 1 -> 8” and “Dex 1 -> 16”.
· Bug fix: the “Rotate Component” buttons are now visible again (they disappeared from the previous version).
· Mouse wheel now controls the signal traces scroll up/down function.
· Bug fix: sometimes, closing the timing diagram window, the “focus” moved to another application, instead to go to the d-DcS main window. The problem has been corrected.
