Simply Voltage Divider

This video show you how to quickly create a voltage divider using 2 resistors and simulate the divider in real-time using a signal generator and an oscilloscope. Click image below to see the video.


New Spice Model Popup (Simulation Menu)


This button allow a popup Spice model editor for a symbol to appear when a symbol is selected. e.g. for a resistor : dragging the slider updates the resistance in real-time (see above video)

New Tutorial Video

This video shows you how to create a simple voltage divider and then use the spice probe to display both the input waveform and output waveform of the divider. Although the circuit is very basic it shows you the elementary principles of creating a circuit and viewing the circuits performance. This design was created using DEX.


Future Plans in a Nutshell

These are the features that I want to complete and finish off:


Python scripting. This full allow me to develop graphical objects you can place inside the schematic that when you click on them, they will run a script. It would be useful to have this also work with simulation.

Loads of videos. These will be tutorial videos and I will incorporate them inside the help system.

Expand the help system so it gives fully comprehensive instructions and reveals the many secrets in DEX.

More parametric parts.

Perhaps STEP 3D import.
