LTC - .lib not recognized..?

[Rene]

LTC Switchercad, on a Vista Notebook:

Strange problem, I made a new transistor:

bcp69.asy

Version 4
SymbolType CELL
LINE Normal 16 64 44 76
LINE Normal 44 76 36 84
LINE Normal 16 64 36 84
LINE Normal 40 80 64 96
LINE Normal 16 80 16 16
LINE Normal 16 32 64 0
LINE Normal 16 48 0 48
WINDOW 0 84 32 Left 0
WINDOW 3 84 68 Left 0
SYMATTR Value bcp69
SYMATTR Prefix QP
SYMATTR Description Bipolar PNP transistor
SYMATTR SpiceModel bcp69.lib
PIN 64 0 NONE 0
PINATTR PinName C
PINATTR SpiceOrder 1
PIN 0 48 NONE 0
PINATTR PinName B
PINATTR SpiceOrder 2
PIN 64 96 NONE 0
PINATTR PinName E
PINATTR SpiceOrder 3


Basically I just modified and renamed the PNP asy.

The bcp69.lib works, I placed it both in the working directory, and in the
LTC "sub" directory.

The lib file works fine when I use the "PNP" transistor, and name it value:
"bcp69", and add:
".include bcp69.lib"

When using the bcp69.asy, I get "Can't find defenition of model "bcp69.lib"

In the netlist, it reverts to ".lib
C:\PROGRA~1\LTC\SwCADIII\lib\cmp\standard.bjt"
Where did that get from?

What would be a nice template?


What silly mistake did I make?


TIA!

I think your prefix attribute should be X.
