Creating Subcircuits from Schematics with TINACloud

In TINACloud you can simplify schematics and hide clutter by turning portions of the schematic into subcircuits.

TINACloud automatically represents these subcircuits as a rectangular block on your schematic.

You can convert any schematic diagram into a subcircuit, called a Macro in TINA, simply by adding the terminals and saving the new circuit in the special (*.tsm) format.

Let’s see how to create a Macro in TINACloud

Load the Half Adder (Half_Add.tsc) example from the TINA Examples folder of TINACloud

To invoke the Schematic Editor Select Schematic Editor… from the Tools menu or double-click an empty spot on the workspace.

The Schematic Editor appears

Delete the diagram and the text. Click the object you want to delete, then press the Delete key or click the X button on the toolbar.

Let’s convert the Half Adder example into a Macro

Delete the old terminals and replace them by subcircuit terminals called Macro Pins in TINACloud

To select the portion of the circuit (terminals) click the Multiple Selection button first then the corner of the the area you want to select, hold down the left mouse button then move the mouse and release the left mouse button at the opposite corner.

Click the X button on the toolbar

Release the Multiple Selection Button

Click the Macro Pin on the Special Toolbar

The Macro Pin will be attached to the cursor and you can move it anywhere on the screen.

You can Rotate the Pin using the Rotate Left or Rotate Right buttons

Connect the Macro Pin to the circuit

When you place the Macro Pins, their label is automatically set to Pin1, Pin2 etc.

Double-click the labels then in the Property window set the label field as shown

Reposition some labels

Next create and save the new Macro.

Press the Insert (+) button

Select Upload macro…

In the Diagram window set the Macro name (in this case: HA)

then click the Upload button

In the pop-up window the following message appears: Macro uploaded.

Click OK

Now, let’s see how to insert a Macro into a schematic and use it

Click the Insert (+) button then select Insert Macro

Select the Macro HA, then press OK.

The newly created macro will be attached to your cursor and you can place it in the usual way.

Let’s modify the name and content of the macro

Create the modified macro under the name HA Circuit

then insert it

The Macro has been already uploaded, but you may save this circuit if you wish. Let’s save under the name HALFADDERModified

Let’s check with an analysis the operation of the new Macro we’ve created

Load the original HALF_ADD tsc. into the

Schematic Editor of TINACloud without the diagram and text in the way as previously shown.

Let’s make more place by using the Zoom out command

Pan the circuit by holding down the left mouse button while moving the mouse.

Insert the newly created HA Circuit Macro

Using Copy and Paste, add the Generators and Outputs of Half_Add.TSC to the Macro.

To draw the wires, click the first connection point, then draw the wire by moving the mouse and finally click the second connection point.

Save the circuit under the name HALF_ADDModified

If you click the macro and press the button in the SubCkt (Content) line you can see the schematic stored in the macro

Finally let’s check with the Digital Analysis the newly created macro

Run Analysis

Digital

You can easily check that the new Macro provides the same result

Using the Schematic Symbol Editor in TINA : Making Your Own Schematic Symbols

Using TINA’s Schematic Symbol Editor, you can create new schematic symbols so that you can add your own circuit components to TINA.  To create new symbols, you place lines, arcs, rectangles, and arbitrary characters with any fonts, specifying line-width, color, and area color fills.  After drawing the symbol, you add and define connections to it.

In this tutorial video we will show how you can create a new symbol for the full-adder circuit (that was used previously in our “Creating Subcircuits from Schematics 2- Macro in Macro” video) and use in TINA.

Watch our tutorial video, with English voice-over and subtitles, to see how  you can create a new symbol for the full-adder circuit  and use in TINA.

Using the Schematic Symbol Editor in TINA:Making Your Own Schematic Symbols

Using TINAs Schematic Symbol Editor, you can create new schematic symbols so that you can add your own circuit components to TINA.

To create new symbols, you place lines, arcs, rectangles, and arbitrary characters with any fonts, specifying line-width, color, and area color fills.

After drawing the symbol, you add and define connections to it.

Start the Schematic Symbol Editor of TINA using the Start menu of Windows 10

TINA Schematic Symbol Editor appears

Now let’s create a new symbol for the full-adder circuit that was used previously in our “Creating Subcircuits from Schematics, part 2- Macro in Macro” video

Draw a rectangle as the body of the component.

Press the Rectangle button then click on any point in the drawing area, hold the mouse button, and move the mouse until the rectangle is properly sized.

You can easily replace the label by using the left-mouse button while dragging it

Fill the rectangle with a color by clicking first the symbol (to be selected),

then the Fill color icon at the lower left corner of the window

Select the color from the Palette then click OK

You can also change the border of the rectangle by using the Object color icon

Let’s not change the suggested border color

Now add the terminals. Select the desired terminal type from the Terminal-Toolbar in the upper left corner of the window and move the cursor into the rectangle you just drew.

Position it using the mouse then click to locate the terminal.

Be sure the small red x, indicating the pin end, is outside the body. Continue this process until every terminal is positioned.

Use the rotate right or rotate left button if it is necessary

Note: the Rotate icons are active after the terminal is placed & still selected

After you have positioned all the terminals, you can establish their properties by double clicking on each of them.

Change the pin name 1 into A in the Pin Properties window, then click OK

You should assign terminal names as shown above

Next, write the name: Full Adder inside the symbol

Click on the Text Editor (T)button on the Toolbar, then click on the macro symbol

Enter the name: Full Adder then click OK

Click the “Auto-calculate sensing rectangle” icon to define the area where you can select the symbol in TINA.

Finally, copy the new symbol into the Symbol library with the Add device button

and by using the Save as command,

save your .ddb file in your Private or Shared catalog folder

under the name Full Adder

Close the TINA Schematic Symbol Editor

Now let’s see how to use the new schematic symbol in TINA

Open TINA

Click the Tools menu

Select New Macro Wizard

Type a name for the new macro

In our case: Full Adder

Change the Settings from Current circuit to From file

Click the Open icon

Select the Main TINA folder

then select the Macrolib folder

Open the Full adder.tsc file

Press the Next button

The wizard finds the built-in Full Adder symbol in the symbol library of TINA

Our newly created Full Adder symbol will be at the end of the list.

Click the Next button

and save the macro (Full adder.tsm) into the default Macrolib folder.

In the New Macro Wizard dialog box now the following message appears:

The macro file is ready for use, it can be inserted by selecting Insert Macro or by pressing the Insert button below.

Click the Insert button

The Full Adder macro will be attached to your cursor. Place it wherever you wish on the

workspace.

To see the content of the macro double-click the macro

then Press the Enter Macro button

The content of the Full Adder macro appears

 Lets test our newly created macro in TINAs Digital interactive mode.

To do this, place 3 High-Low digital switches from the Switches Toolbar, one for

each of the A,B & Ci inputs, and 2 logic indicators from the Meters Toolbar

Now select the Digital interactive mode with the narrow „Select Interactive mode”

button on the toolbar and then press the DIG button

The logic levels of the nodes appears, Red for High. Blue for Low.

Click the switches to change the input states.

The logic indicators will also show the logic level of the outputs in a Red square for

High, and empty square for Low.

The Half adder circuit works as required.
