In TINA you can also create your own components from any Spice models given in .MODEL format that you have made or downloaded from the Internet. <br /> <br />Watch our tutorial video to see how to create a TINA macro component using a BC846 NPN Bipolar transistor downloaded previously from the web. <br /> <br />You can also find below the script of the video: <br /> <br />Creating Subcircuits from Spice Models: .MODEL format <br /> <br />In TINA you can also create your own components from any Spice models given in .MODEL format that you have made or downloaded from the Internet. <br /> <br />Some device models are stored in Spice .MODEL format. Let’s download one from the internet and add the model to TINA <br /> <br />Here is the model of the BC846 NPN Bipolar transistor <br /> <br />Let’ save this model <br /> <br />In Google Chrome click the right mouse button. <br /> <br />In other browsers find the Save as command <br /> <br />Select Save as… <br /> <br />Save it as a .mod file, as this is the extension that TINA expects <br /> <br />Let’s see how to add this model to TINA after starting the program <br /> <br />Click the Tools menu <br /> <br />Select the New Macro Wizard <br /> <br />Enter the name of the model BC846 <br /> <br />Change the Settings from Current circuit to From file <br /> <br />Click the Open icon <br /> <br />Select the Downloads folder where the BC846.mod file is saved <br /> <br />Switch the Files of type into (*.CIR; *.LIB; *.MOD), then enter the file name BC846.mod <br /> <br />Click Open <br /> <br />Now click Next <br /> <br />Note that into the TINA Macros folder you can save with Administrator rights only. <br /> <br />So select User Macros <br /> <br />then click Save <br /> <br />In the New Macro Wizard dialog box now the following message appears: <br /> <br />The macro file is ready for use, it can be inserted by selecting Insert Macro or by pressing the Insert button below. <br /> <br />Now click the Insert button <br /> <br />the Macro will be attached to your cursor and you can place it wherever you wish on the workspace <br /> <br />Double-click the Macro & click Enter macro to see its content <br /> <br />A small schematic design inside the macro appears <br /> <br />Double-click the Transistor <br /> <br />then press the … button in the Type line <br /> <br />Here you can see the detailed description of the model which has been downloaded from the internet <br /> <br />Let’s close the Model Parameters window <br /> <br />Click the Close icon on the Toolbar if you wish to close the Macro and go back to the Schematic Editor of TINA <br /> <br />You can also Insert the new model using the Insert Macro command. <br /> <br />Select Macro from the Insert menu <br /> <br />From the Macrolib folder select BC846.TSM and press Open. <br /> <br />The new model will appear attached to your cursor and you can place it anywhere on the workspace. <br /> <br />This how you can add a device model in .MODEL format. You can similarly add any Spice models, diodes, transistors, MOSFETS etc. which are defined by the standard Spice .MODEL format. <br /> <br />You can also add such models to TINACloud. <br /> <br />Note: <br /> <br />It is of course not necessary to add devices with .MODEL definition one by one. You can also add a number of such devices in one step using the Library Manager of TINA. This process will be demonstrated in a separate video and also described in chapter 5.3 of the Users Manual of TINA. However if you n
