How to create a Spice component with the SUBCKT model embedded?

Hi, I've designed this circuit for simulation (find the circuit here [https://easyeda.com/jmgonet/high-side-pmos-driver):](https://easyeda.com/jmgonet/high-side-pmos-driver) The simulation runs as I intended, but I had to place a big text area with the content of the .SUBCKT model in the schematics. Actually, there are two active components in the: * The BC547C, which exist in the System Library an Spice Component, and I could directly use in my circuit. * The IB9343, which doesn't exist. So I took the "GENERIC SPICE .SUBCKT PMOSFET SYMBOL (ENHANCEMENT)" from the System Library, then I changed the model name, and I pasted the .SUBCKT file that I downloaded from Infineon. So this is my question: How can I create a new "Spice Component" and embed the .SUBCKT model in it, so I (or anyone) can use it without further manipulation, just like the BC547C?

If you study the sections on Device Models and on Schematic symbols: prefixes and pin numbers, this explains ways to do what you want. To make a permanent part please post a link to the spice model and I'll build a symbol and put the model in the system library. :)

There are now spice symbols with associated spice subckts for: [IRLRU9343](infineon.com/cms/en/product/power/mosfet/20v-250v-p-channel-power-mosfet/irlr9343/) [IRLIB9343](https://www.infineon.com/cms/en/product/power/mosfet/20v-250v-p-channel-power-mosfet/irlib9343/) in the library.

Wow, thank you! That was helpful. I'm impressed: each time I had a problem with simulation, there you were to help me out. Best regards,   Jean-Michel.
