Crocodile Technology 3D is an electronics simulator program for Windows that covers all aspects of the design process in 3D. It includes a considerable amount of circuit boards, editing tools, as well as PIC microcontroller simulation, testing and programming.

Creating a PCB project

Whether or not you plan to simulate a printed circuit board in 3D, you will find the 2D electronic simulation instruments very useful. In order to create a PCB, you need to drag the desired components from the toolbars, draw wires between terminals with the mouse and edit component values and properties.

If you just want to simulate or test a circuit, you can use exactly the same tools. Similar to PCB Artist, with this utility you are able to choose from a range of different components, to fit with the real modules you are using.

Microcontroller programming

This application integrates programmable control with electronics, allowing you to modify microcontroller chips such as PICAXE or PIC. All programs are created using a simple flowchart interface. To begin, you can choose a Start command and then follow the other development stages.

Editing of commands and expressions is very straightforward, all you need to do is click on the desired entry. Additionally, you are able to use subroutines to create more complex programs as well as introduce variables to store numbers.
