i want to design a power amplifier in Tanner L-Edit.
I want to write code in the .ext file but I don't know what syntax or language the .ext file is expecting. Is it spice? I couldn't find a good tutorial.

Device = Mosfet Channe = N Single Transistor Length = 1.00 Single Transistor Width = 22.00 Transistor Multiple Count = 22 Bulk Pattern = 0 Gate Finger Pattern = 0 Source/Drain Finger Pattern = 0 Generated by: Dev-Gen ver. 14.11
If I check the SPICE paramter back annotation as in this screenshot:
All I get is the error (when I choose the .ext file
Extract definition file is not selected.
Please click Browse EXT File button to select the file.
