Sim800l - Proteus Library

Once you have downloaded the library files (typically .LIB, .IDX, and possibly .HEX), follow these steps:

Step 1: Locate Proteus Library Folder

Step 2: Copy Library Files

Step 3: Copy Model Files (If Any)

Step 4: Restart Proteus

Step 5: Verify Installation

Alternative Method – Using Library Import Tool:

This is the closest you will get to a library. You write a Python or C# script that acts as the SIM800L. sim800l proteus library

Hardware Setup in Proteus:

Software Setup (Outside Proteus): Write a script that listens on COM5. When it receives AT\r\n, it replies \r\nOK\r\n. When it receives AT+CMGF=1, it replies OK. When it receives AT+CMGS="+123456", it replies \r\n> .

Result: Your Proteus simulation thinks it is talking to a real SIM800L.

By default, Proteus does not include a native GSM module in its component library. If you search for "SIM800L" in the standard Proteus PICK DEVICE window, you will find nothing. This creates a barrier for students and hobbyists who want to design and test GSM-based systems without hardware.

A dedicated SIM800L Proteus Library solves this by providing:

Without this library, you cannot run a single line of GSM code in simulation.

Once downloaded, you need to place the files in your Proteus LIBRARY folder. Once you have downloaded the library files (typically

  • Paste the files inside the LIBRARY folder.

    • Copy the SIM800L.LIB and SIM800L.IDX files into the LIBRARY folder.

    The SIM800L Proteus library is an invaluable tool for embedded developers, educators, and hobbyists, despite its limitations. While no simulation can fully replace physical testing, it can catch 80% of logic and wiring errors before they burn hardware.

    To recap:

    Whether you are building a remote weather station, a vehicle tracking system, or a smart irrigation controller, simulating your SIM800L-based design in Proteus will save you time, money, and frustration. Start simulating today, and watch your IoT ideas come to life – virtually first, physically second.

    Here is a simple Arduino sketch to test your library by sending an SMS.

    // SIM800L Simulation Test on Proteus
// Sends "Hello Simulation" to a virtual phone number

    #include <SoftwareSerial.h>
    

    // Use software serial for flexibility, or hardware serial (Serial1 on Mega)
SoftwareSerial sim800(10, 11); // RX=10, TX=11 Step 2: Copy Library Files
    

    void setup() 
Serial.begin(9600);   // For debugging on Serial Monitor
sim800.begin(9600);   // SIM800L default baud rate
    

    Serial.println("Starting SIM800L Simulation...");
delay(2000);
    

    // Send AT command to check communication
sim800.println("AT");
delay(1000);
    

    // Set SMS to text mode
sim800.println("AT+CMGF=1");
delay(1000);
    

    // Send SMS to a simulated phone number (any string works in simulation)
sim800.println("AT+CMGS="+1234567890"");
delay(1000);
    

    // The SMS content
sim800.print("Hello from Proteus Simulation!");
delay(500);
    

    // Send CTRL+Z (ASCII 26) to indicate end of message
sim800.write(26);

    

    void loop() 
// Forward responses from SIM800L to Serial Monitor
while(sim800.available()) 
Serial.write(sim800.read());
// Forward user input to SIM800L (optional)
while(Serial.available()) 
sim800.write(Serial.read());
