In this post, we will show you how to seamlessly convert Proteus circuits into TINACloud.

By converting these circuits into TINACloud, you can instantly run and analyze them anywhere-without any installation-on virtually any device, including PCs, laptops, tablets, and smartphones, regardless of the operating system, whether it’s Windows, macOS, iOS, Android, or more. All you need is a modern web browser.

It is important to note that this conversion process is also available in the offline version of TINA, allowing you to perform the transition locally.

The resulting .TSC files are fully cross-compatible, providing a seamless workflow between the offline desktop software and the online TINACloud environment. 

Click here or on the image above to watch this blog presented as a video tutorial.

Example 1: Educational RLC Circuit

TINACloud includes several ready-to-use sample circuits, which you can find under the Examples/3rd Party files/Proteus folder.

Let’s start with a simple educational RLC circuit. This is how the circuit looks in Proteus.

1. Importing the Circuit

• Navigate to the Examples / 3rd Party files / Proteus folder.
• Select the RLC circuit file (RLC.pdsprj) and click Open.

After conversion, the circuit is reproduced exactly in TINACloud, as shown here:

2. Running a Transient Analysis

First, we will run a Transient Analysis. Go to the Analysis menu and select Transient… As soon as the simulation completes, the resulting time-domain waveforms are displayed cleanly on the screen.

Using the Collect Curves command from the View menu in the Diagram window, you can also plot the input and output waveforms on the same coordinate system.

You can also label the curves with their signal names using the Auto-Label Curves icon in the Diagram window.

3. Configuring AC Analysis

Next, let’s explore the frequency domain. Navigate to the Analysis menu and select AC Analysis > AC Transfer Characteristic…

In addition to standard AC Bode plots, TINACloud features advanced calculation capabilities, allowing you to easily generate Amplitude, Phase, Nyquist, and Group Delay diagrams.

Select the AC Bode, Amplitude, Phase and Nyquist diagrams, and set the start frequency to 10 kHz and the number of points to 1,000 for a high-resolution output, then click Run to execute the analysis.

Four separate tabs will appear, displaying the Amplitude, Phase, Nyquist and Amplitude & Phase (Bode) diagrams.

4. Symbolic Analysis in TINA and TINACloud

A unique feature of TINA and TINACloud is the ability to derive a circuit’s Transfer Function symbolically, presenting it as an exact mathematical formula. This allows engineers and students to gain deeper insights into circuit behavior-including poles, zeros, gain, and frequency response. This symbolic expression can also be used for analytical studies, documentation, optimization, and verification, moving beyond a sole reliance on numerical simulation results.

Note: While symbolic transfer function derivation is only possible for linear circuits, you can still analyze active filters implemented with op-amps. In TINA and TINACloud, nonlinear operational amplifier models are automatically replaced with ideal op-amp models during symbolic analysis. This provides highly accurate results, allowing the transfer function to be derived and analyzed symbolically.

Running Symbolic Analysis

To perform Symbolic Analysis, open the Analysis menu, select Symbolic Analysis, then Symbolic AC Transfer, and run the analysis.

The analytical form of the Transfer Function will immediately be displayed on your screen.

You can now insert the symbolic expression into the TINACloud Text Editor and place it directly onto the schematic, making the analytical results part of your circuit documentation. In the Symbolic Result window click on the “Send to” tab then select the “Text editor”.

Note that the formula can also be edited within the Text Editor, though we won’t cover those editing features in this tutorial.

Once the formula appears in the Text Editor, click OK. The formula is now attached to your cursor. Position it wherever you like on the schematic, and left-click to place it.

Plotting and Comparing Results

Beyond formulas, you can also plot the analytical transfer function to compare it directly with your numerical simulation results.

In the Symbolic Results window, simply click the Draw Diagram button. The plot of the Transfer Function will appear. To make comparing the analytical and numerical results easier, click on the curve and change its color to green. Next, click the curve again, then click the Copy curve icon to save it to your clipboard. Now, switch back to the previously calculated Ampl 1 tab, and use the Paste Curve icon to overlay the symbolic result directly onto the numerical curve.

As you can see, the two curves match perfectly within the line width.

Example 2: Active Band-Pass Filter

For our next example, we’ll look at a band-pass filter, built around the Analog Devices ADA4000-1 operational amplifier. This circuit is a standard building block for what we call active filters, and here is what it looks like in Proteus:

File Import and Conversion

To bring this into the TINACloud workspace, save the circuit to your local Downloads folder. Next, use the Upload command to convert the file.

After conversion, the circuit is reproduced in TINACloud, as shown here.  

Next, save it as ‘Active Band-pass Filter.tsc’.

Running AC & Symbolic Analysis

Since the setup is similar to our previous example, we’ll focus just on running the AC and Symbolic Analyses for this simulation. We’ll start with the AC Analysis, which generates our combined Amplitude and Phase Bode Plot.

Go to the Analysis menu, select AC Analysis, AC Transfer Characteristic. Click Run.

The combined Amplitude and Phase Bode Plot appears.

Next, run the Symbolic AC Transfer Analysis. Just as we explained in the last video, TINA and TINACloud automatically swap out the nonlinear ADA4000-1 for an ideal op-amp. This substitution makes symbolic analysis possible, allowing TINACloud to generate the analytical transfer characteristic.

Plot Visualization

Now, let’s compare this analytical result with our numerically calculated Bode Plot. In the Symbolic Result window click the Draw Diagram  tab. Three plots will appear: the Amplitude, the Phase and the combined Bode Plot.

Comparing and Overlaying the Curves

To easily compare the two methods, first change the color of the analytical Amplitude Plot to green, and copy the curve to your clipboard. Then, switch over to the numerically calculated Bode Plot tab, and paste the green curve directly into the Amplitude Plot.

Repeat this exact same procedure for the Phase Plot.

Final Analysis and Conclusion

When you look at the results, you can see that the numerically calculated curves align perfectly with the analytical curves. As we’ve emphasized in previous videos, this excellent agreement demonstrates exactly why ideal operational amplifiers are so widely used in active filter synthesis.

Example 3: 8-bit PIC Microcontroller

Our final example features an 8-bit PIC Microcontroller (MCU). Here, we will demonstrate the conversion to TINACloud, but a very similar conversion process is also available in the offline version of TINA. The resulting .TSC files can be opened and run in both TINA and TINACloud.

The converted microcontrollers are fully operational in both the offline and cloud versions of TINA.

Now, open the PICLedBlink.pdsprj file from the TINA Examples\3rd Party files\Proteus folder.

Once the conversion is complete, press the TR button, and you’ll see the LED begin to blink immediately. TINACloud also allows you to study the code execution using the built-in MCU Debugger:

Enable MCU Code Debugger in the Analysis menu. Press the TR button again to launch the debugger window.

• From here, you can use the Step button to execute code line-by-line while monitoring Registers and Memory.
• You can also set Breakpoints by clicking on a line of code or using the Breakpoint button.
• Press Run, and the program will halt at your designated points. Pay close attention to Port B, which directly controls the LED.

Programming MCUs in C

While Assembly is powerful, you can also program MCUs in TINACloud using C.

Let’s open the PICLedBlink_CCode.pdsprj file. This circuit looks identical to the previous one, but the PIC is running on C-code. Double-click the MCU, click the “…” at the end of the MCU-code line. Here you can upload your C code or preview existing code. For now, let’s preview the code that’s already been uploaded.

Note that in both TINA and TINACloud, C code can be debugged just like assembly code-either by executing it step by step or by using breakpoints.

In addition to PIC microcontrollers, TINA and TINACloud support more than 1,400 microcontrollers, including: AVR, 8051, HCS, ARM, Raspberry Pi, ESP32, ST, Arduino, XMC, and more.

Conclusion

This concludes our tutorial on converting Proteus circuits and running them in TINACloud.
Please note that the same procedure also works in the offline version of TINA, and the resulting .tsc files are fully compatible with both TINA and TINACloud.
