Getting Started with Proteus

Thanks for this article to archeng504


After installing Proteus , run ISIS Proteus Professional, will appear the following window interface :



Following is a brief description of each part of the function :

1. Schematic Editor window (The Editing Window): As the name implies , it is used to draw the schematic . Blue box as editable area, to put it inside the component . Note that this window is no scroll bar , you can use the preview window to change the schematic visual range .

2. Preview window (The Overview Window): It shows the two elements, one is this: When you are in the component list, select a component, it will show a preview of the element ; Another is that when you mouse focus falls on the principle diagram editor window ( ie, place the component into the schematic editor window Or after the Schematic Editor window, click the mouse ) , it will display the entire schematic diagram of the thumbnails, and will show a green box , green box which is the content of the current diagram window displays the contents of Therefore, you use the mouse to click on it to change the location of the green box , thereby changing the schematic visual range.




3. Model Selection Toolbar (Mode Selector Toolbar):

Main Modes:

1 * Select elements (components) ( selected by default )

2 * Place the connection point

3 * place a label ( the bus will be used )

4 * Place text

5 * for drawing bus

6 * for placing subcircuits

7 * for instant editing component parameters ( first click on the icon and then click the element you want to modify )


1 * terminal interface (terminals): There VCC, ground , output, input and other interfaces

2 * Device Pin : for drawing pin

3 * Emulation chart (graph): used for various analyzes, such as Noise Analysis

4 * recorder

5 * signal generator (generators)

6 * Voltage Probe: to be used when using simulation charts

7 * current probe : Using simulation to be used when using simulation charts

8 * Virtual Instrument :  in the image above, an oscilloscope

2D graphics (2D Graphics):

1 * Drawing Lines

2 * draw a variety of boxes

3 * draw various circles

4 * draw a variety of arc

5 * draw various polygons

6 * draw various text

7 * draw symbols

8 * paintings origin , etc.

4 . Component List (The Object Selector):

For the selection of components (components), terminal interface (terminals), the signal generator (Generators), simulation chart (graph) and so on. For example , when you select ” Component (Components) “, click the ” P ” button will open the selected component dialog box, select an element after ( click on the ” OK ” after ) , the device will be displayed in the list of elements , later to use this element, just in the component list can be.

5 . Toolbars direction (Orientation Toolbar):

Rotate :

The rotation angle can be an integer multiple of 90 .


Flip Horizontal and vertical flip finish . Use: Right-click the component , and then click ( left-click ) the corresponding rotation icon.

6 . Simulation Toolbar

1 * Run

2 * single-step operation

3 * Pause

4 * Stop

AVR microcontroller simulation example:

We want design an AVR driver for a LCD1602 and monitor it with an oscilloscope data lines. Parts of file formats generated by the compiler are different, such as ICC is COF, IAR is D90, GCC is COF, ELF. Proteus supports files COF, D90, HEX , etc.

Run Proteus Professional , the following window appears :



1, Add the components, in this case ATMEGA16, LM016L (LCD1602), after we’ ll add the oscilloscope.Click the “P” button to select Component dialog box appears


KEYWORDS of the dialog box , enter the ATMEGA16, get the following results :


Click OK, and close the dialog box , then the components listed in the list ATMEGA16, also find LM016L. The end result :

2 , place components: the component list, select Left ATMEGA16, in the schematic editor window, click the left button , so ATMEGA16 is placed in the Schematic Editor window . Similarly placed LM016L.


Add “ground” : Left Select model selection toolbar icon appears:

Left selection GROUND, and in the schematic editor window, left-click , so that the “ground” was placed into the Schematic Editor window .

Add Oscilloscope: Left Select model selection toolbar icon appears:

Left selection OSCILLOSCOPE, and in the schematic editor window left click , so that the oscilloscope is placed to the Schematic Editor window.

place components paying attention to place them inside the blue box of workarea.

3 . Connection. AVR, LCD ‘s VSS, VDD, VEE don’t need connections , the default VSS = 0V, VDD = 5V, VEE =-5V, GND = 0V

4 . Add a simulation file. Right click before on ATMEGA16 then select Edit Properties

in the Program File , click the File Browser dialog box, locate lcd_C.hex file, click OK to finish adding files.Set Clock Frequency at 8MHz, click OK to exit.

5 . Simulation

Click Start simulation :

Description: red for high, blue represents low, gray represents uncertainty level (floating). Running in the Debug menu, you can view the AVR related resources.

6 , the source code debugging

Proteus supports COF file debugging. Be sure to create this file in your compiler options.Complete the schematic drawing and add debug files (COF file ) , click:

the AVR Source Code window appears , if the state does not appear in the debugger , go to Debug menu to find .


Let’s say something about these icons

1 * continuous operation , it will exit the single-step debug state , and close the AVR Source Code window

2 * single-step operation , skip directly encountered Functions

3 * single-step operation , will enter its internal encountered Functions

4 * out of the current function , when using 3 * into the internal function , use it immediately on exiting the function returns a function , it should be seen in conjunction with the 3 *

5 * run to the line where the mouse

6 * Add or remove a breakpoint , the breakpoint is set using the program will stop at the breakpoint.
