Using the Library Manager of TINA, Part 3: Adding complete Spice libraries in .MODEL format, now with English voice over

Semiconductor device manufactures often provide models for their components in .MODEL format. These are normally placed in a text file (also called library) containing many .MODEL instructions.

In this tutorial video we will show how to add such libraries to TINA. Of course you can also create your own models in .MODEL format and add to TINA in a similar way.

Using the Library Manager of TINA, Part 2: Adding a Complete Spice Library, now with English voice over

In most cases adding a Spice library to TINA is very simple. Using the comments in the models, everything is automatically recognized in the Library Manager and adding a whole library to TINA takes a few minutes only.

In the following tutorial video after showing this general case we will also show how to add models where it is not possible automatically to find the connection between the Spice models and their graphic symbols.

Watch our tutorial video to see how to add a whole Spice library to TINA.

New! Analysis links in TINACloud

A new exciting feature in TINACloud that now you can add links to your circuits which allow you to carry our most TINACloud analyses simply by clicking the links without using TINAclouds’s menus. This feature is extremely useful when you create presentations for your customers.

 

 

In the above window click any of the underlined links to experience the new feature.

For example if you click the “Click here to run AC nodal analysis” link the following screen will appear.

AC Node voltages

By default is shows the rms voltage on the output(s). If you click with the cursor on any nodes (yellow boxes) of the circuit it will display the detailed nodal analysis data in a small window. Click You can repeat this any times until you press the Close button to finish the Nodal Analysis.

Further if you click the “Click here to run AC transient analysis” link, the Transient analysis will automaticall run and the following screen will appear. You can now run cursor on the diagram or close the diagram and make further analyses.

Mixed Circuit Simulation in TINA and TINACloud (Spice – HDL – MCU co-simulation)

TINA  includes a very powerful mixed mode circuit simulator engine. It is based on the XSPICE mixed mode algorithm, extended with MCU and HDL (VHDL, Verilog, Verilog A & AMS) components. In your circuits you may freely mix any analog or digital components of TINA, including microcontrollers (MCUs) and macros with Spice or HDL content. You can modify these components on the fly along with the code in the MCUs. TINA will analyze the analog parts in analog, the digital parts in digital, and will automatically create the interfaces among the components. This ensures synchronization and fast convergence.

Let’s explore some of the uses of this mode through a few examples.

1. Waveform generation with VHDL and Spice subcircuits

The following circuit generates an analog sine or sawtooth signal depending on the status of the left SW-MODE switch:   Mixed Mode Simulation in TINA and TINACloud-blog5

 Click the picture to run this circuit online with TINACloud

The Digital Wave box on the left of the circuit includes VHDL code with a lookup table (Sine_LUT ) for the sine wave and a counter for the sawtooth signal. The essential part of the VHDL code is:  

   process(Reset, Clk) 
   begin 
       if (Reset = '1') then 
           Wave <= (others => '0'); 
           LUT_index <= 0; 
       elsif rising_edge(Clk) then 
           if (Enable = '0') then 
               Wave <= (others => '0'); 
           elsif (Sel = '0') then 
               Wave <= Sine_LUT(LUT_index); 
           else 
               Wave <= conv_std_logic_vector(LUT_index,5); 
           end if;
           if (LUT_index = LUT_index_max) then 
               LUT_index <= 0; 
           else 
               LUT_index <= LUT_index + 1; 
           end if;
       end if; 
   end process; 
   d0 <= Wave(0); d1 <= Wave(1); d2 <= Wave(2); d3 <= Wave(3); d4 <= Wave(4);

 The digital output of the counter is converted into an analog signal in the 5 bit DA converter of TINA shown in the middle of the circuit. The DAC sine wave output needs to be cleaned up with a low pass filter. We will use a Spice opamp model of the TL081 in a Sallen and Key low pass filter configuration. Press the Enter Macro button on the property dialog and TINA will open the macro. You can review and, if necessary, modify the Spice code inside the macro.

Here are the final waveforms of the full circuit, including the five counter output waveforms. SW_MODE is in the High state, selecting the sawtooth signal:

If we change the SW-MODE switch to Low and run Transient analysis again, the waveforms are:

To see the effect of the analog filter, delete curves d0 to d4 from the diagram by clicking the curves and pressing the Del key:

2. MCU controlled SMPS circuit

The mixed mode simulator of TINA not only allows MCUs, but also any linear or nonlinear parts in TINA’s libraries. As an example, let’s study the following circuit, which realizes a DC-DC converter, converting 5V DC to 13V DC, and operating in boost mode:

Symbolic Analysis of Analog Circuits using TINA

TINA Design Suite is a powerful yet affordable circuit simulator and PCB design software package for analyzing, designing, and real time testing of analog, digital, HDL, MCU, and mixed electronic circuits and their PCB layouts. You can also analyze SMPS, RF, communication, and optoelectronic circuits; generate and debug MCU code using the integrated flowchart tool; and test microcontroller applications in a mixed circuit environment.

A great number of  electrical engineers find TINA an easy to use, high performance tool, while educators welcome its unique features for the training environment. TINA also includes a unique feature, Symbolic Analysis.

symbolicanalysis10-blog

  Symbolic analysis producing the closed form expression of the transfer function

Symbolic analysis produces the closed form expression of the transfer function, equivalent resistance, impedance, or response of analog linear networks. In DC and AC analysis mode, TINA derives formulas in full-symbolic or semi-symbolic form. In transient analysis, the response is determined as a function of time. Circuit variables can be referenced either as symbolic names or by value on a component-by-component basis. Through symbolic analysis, poles and zeros of linear circuits can be calculated and plotted. You can efficiently prepare reports and paper presentations by printing or by copying and pasting your expressions to any Windows program.

Watch our tutorial video to see how to use the Symbolic Analysis of  Analog Circuits in TINA.
