Raspberry Pi is a powerful, compact minicomputer. It is affordable, runs various operating systems and it is perfect for learning or projects.
It can also run Windows applications using the Wine Windows emulator. Including TINA.
Wine originally an acronym for „Wine Is Not an Emulator” is a compatibility layer capable of running Windows applications on several operating systems, such as Linux, macOS.
In this video we will create and test a Half Adder circuit in TINA.
Drawing the Schematic Diagram of the Half Adder circuit
To start with, we will draw the schematic diagram of the half adder. We will use an XOR gate for the Sum and an AND gate for the Carry, High-Low switches and Voltage pins for the outputs.
Testing the circuit
First, we test the circuit interactively using the interactive mode of TINA. We play with the switches toggling between Low and High levels to produce all the input combinations.
Switches are toggling between low and high levels
Next, we run a Digital Timing Analysis from the Analysis menu. As a result all signals are displayed separately in a time diagram.
In this video we will create and analyze an RLC circuit on the Raspberry Pi 5 single board computer with TINA.
First you have to install the Wine Windows emulator available from the PI-Apps application.
If Wine setup is complete you will see it in the Raspberry OS main menu, so for example you can launch the program WineCfg to configure the optimal text size of the emulated Windows applications.
Assuming you have Wine working in 64-bit mode, you can start the installation of TINA. After completion of the TINA installer, you’ll find TINA in the Raspberry OS main menu (if not in the first level menu, look for it in Wine applications) so you can start it from there.
Creating the RLC circuit
An RLC circuit is an electrical circuit consisting of a Resistor (R), an Inductor (L) and a Capacitor (C). After creating the circuit, we change the default values of some of the components.
Transient Analysis
We Set End display time to 50 microseconds, then select the “Zero initial values”option. Next, we add the diagram to the Schematic Editor window to store it together with the circuit schematic.
Symbolic Analysis
After that, we generate the accurate closed formula describing the transient response using the Symbolic Analysis capability of TINA. Note that the closed formula exists in linear circuits only. The symbolic result describes the transient response of the circuit with an accurate analytic closed formula.
In the following, we will show, how to Draw a diagram using the formula and compare it with the numerical result.
AC Analysis
In the AC Transfer Analysis dialog, set the number of points to 500 to have a finer diagram. Using the checkboxes in the diagram group, you can determine which diagrams will be displayed. Check them all.
The AC Amplitude Characteristic appears, but at the same time the program has calculated the Phase, Nyquist, Group Delay and the AC Bode diagrams.
Symbolic Analysis
Finally, we generate the closed formula of the AC Transfer Function using Symbolic Analysis.
In this video we demonstrate the online design and simulation of the Semtech TS30012 DC/DC synchronous switching regulator evaluation circuit using TINACloud.
Startup Transient Simulation
The startup transient of a DC-DC converter is the period of time during which the converter is transitioning from its off state to its steady-state operating condition.

Redesigning the circuit
Let’s redesign the circuit to generate a 3.3 V output voltage. The Design Tool changed the RTOP resistance to 26.7k and displayed a quick diagram of all the relevant analysis results, based on analytic calculations.

Steady State Analysis
Steady state analysis of a DC-DC power supply is the analysis of the circuit’s behavior when it has reached a steady state. This means that the output voltage is constant, except for the ripple voltage, and all the components in the circuit are operating in their steady state conditions.

In this new video we demonstrate the online design and simulation of the Würth MagIC (171033801) DC/DC synchronous switching regulator evaluation circuit using TINACloud.
Startup Transient Simulation
The startup transient of a DC-DC converter is the period of time during which the converter is transitioning from its off state to its steady-state operating condition.
In most simulators the Startup Transient simulation takes a long time since the whole process from the initial state to steady state is simulated.
However due to the built in average model in TINA and TINACloud the simulation takes only seconds both online and offline.
TINA and TINACloud can also be used to perform switching mode transient analysis. Due to the advanced multicore solvers in both software, switching mode transient analysis is still quite fast and results in more detailed waveforms.
In addition, TINA and TINACloud include a very fast calculation of the ripple voltages using the combination of the average and switching models.

Steady State Analysis
Steady state analysis of a DC-DC power supply is the analysis of the circuit’s behavior when it has reached a steady state. This means that the output voltage is constant, except for the ripple voltage, and all the components in the circuit are operating in their steady state conditions.
TINA and TINACloud provide a very fast and accurate method for determining the ripple voltages in any circuit. They use built-in average models to quickly reach the steady state and then switching models to determine the ripple voltage.
This method allows a very fast determination of ripple voltages for any circuit settings without the need of storing initial values of inductors and capacitors in the circuits.
The diagram shows the Ripple voltages and current of the outputs.
