Make/Modify a Component in Proteus (2D Graphics) In this article, a user-friendly feature in the Proteus software is presented, which is the Make Device. For this purpose, 2D Graphics mode of the software is used. In this article, existing components are selected and their schematic view is modified. By using the 2D graphics mode, one can design various blocks that are useful for presenting their prototypes. By using this mode, the colour, shape, size and text related to the component can be modified. This makes the presentation more attractive and perceivable. Some of the possible modifications are explained step-by-step in the following examples, Modifying the view of a Relay Editing an IC or a Microcontroller Creating UART Modules by modifying the COMPORT Modifying the view of a Relay Let’s begin with a simple component, the Relay. In this example, the shape and the orientation of the component are modified. A basic relay contains a coil and an SPDT switch. Now, the position of the coil and the switch are modified in this example. The expected view is shown below and the below procedure explains how to transform from the actual view to the expected view.   Step1: Select the component from pick devices tab.     Step2: Place the component on the worksheet. Right-Click the component and then select the ‘Decompose’ option from the Right-Click Menu.     Now, the individual segments or parts of the component get decomposed. So, these parts are now movable or editable. Select the individual parts and drag them to get the expected view. Step3: Select all the parts of the expected view. Right-click the selected part and then select the ‘Make device’ option from the Right-click Menu.     Step4: Through a series of options the name of the component, Index and other reference parameters can be edited or left unchanged. After this step, the component is created in the library and can be used a regular component by placing it in the workspace. The decomposed component can be deleted. Now, let’s verify whether the modified component works similar to the default component or not. Below is the simulation video that compares the operation of modified and default components. The procedure to modify the component is also shown. Verification and Modifying the View of Relay – Video Demo   Editing an IC or a Microcontroller In the previous example, we have seen the basic modifications like changing the shape through drag and drop option and changing component properties like the voltage. Now, let’s go to next level of modification. In this example, a microcontroller is modified. We can convert the existing microcontroller into a development board. The colours, shapes, pins/terminals layout can be changed. The actual and expected views are shown below. The component is modified such that it looks like a development board in DIP view.   Step1: Select the component from pick devices tab.   Step2: Place the component on the worksheet. Right-Click the component and then select the ‘Decompose’ option from the Right-Click Menu.   Now, the actual component is split into basic parts. It is the combination of several pins/terminals and a rectangular block. The component properties are displayed after decomposing the component. The pin orientation can be modified by mirror option in its Right-Click Menu. Select the pin to be modified or shifted from one side of the rectangular block to the other side, then Right-Click and select X-Mirror option. Below is the procedure to ‘mirror’ the pin/part in X-direction.   There are some hidden pins like Vcc and GND. If desired, these pins can be shown along with... read more
