LTSpice Including .txt files


New Member
I'am trying to include BC237 diode from BC237.txt on LTSpice, but i have a trouble.

I put the BC237.txt on the same directory that i am currently working.

But it is not working. Can anyone help me?

A few things that could be wrong, but try adding the statement ".inc BC237.txt" (without quotes) to the schematic.

If you view the BC237.txt file and it includes the statement ".subckt", then change the symbol's "Prefix" attribute to an "X".

The .txt file has to include the appropriate Spice statements that model the device.
