Creating Subcircuits from Spice Models with TINACloud: .MODEL format

In TINACloud you can  create your own components from any Spice models given in .MODEL format that you have made or downloaded from the Internet.

Some device models are stored in Spice .MODEL format.

Let’s download one from the internet and add the model to TINACloud

Here is the model of the BC846 NPN Bipolar transistor

Let’ save this model

In Google Chrome click the right mouse button.

In other browsers find the Save as command

Select Save as

Switch the Save as type into All files

and Save it as a .cir file, as this is one of the extensions that TINACloud expects.

Start TINACloud

To invoke the Schematic Editor

Select New from the File menu

The Schematic Editor appears

Click the Insert button denoted by a  green + sign to invoke the Insert menu

Select Upload macro

Let’s name the new Macro as BC846

Switch into From File from Current Circuit

then Click Choose Files

Enter BC846.cir into the file name field , then click Open

Now click Upload

In the dialog box the following message appears: Macro uploaded.

Click OK

You can simularly add any Spice models in Spice .MODEL format.

Let’s check how to insert the new model into TINACloud.

Select Insert macro from the Insert (+) menu

Now select BC846 then press OK

The new component will appear attached to your cursor and you can place it anywhere on the workspace by moving the mouse and clicking the left mouse button.

Now let’s create the following test circuit by adding a few more components to test the new model.

Select the Resistor from the Basic Toolbar

Use the Rotate left or Rotate right icon then hold the left-mouse button down while moving it and connect it to the Transistor

Repeat this procedure for R2 & R3

Double click the Resistances (R1 & R2) and in their Properties window set the parameters as shown

R2=47k; R3=3k

click OK

Now select the Ground and connect it to the Transistor

Next add the remaining parts and the wires

then Click the Save button to save the file

Let’s save it under the name BC846_test.tsc

Let’s test this circuit using DC Interactive mode.

Press the DC button

The model works as expected.
