Hi all,
I'm trying to simulate a circuit which consists an transistor.
after running the simulation I see that the the transistor doesn't exist
in the netlist and therefor I get the error of:
" Node N16280 is floating"
I tried adding various 10meg resistor's which didn't change anything.
I tried using other versions of the transistor with no success.
Other simulations I tried work fine. I can't manage to upload the files of the project so
I'm attaching the *.out file and a capture of the circuit.

What can the problem be?
Thanks,
Amitai

Looks like you are using transistor.olb to instantiate the BJT.
The library is not meant for simulation flow.
For simulation purpose you should use libraries from location - <install>/tools/capture/library/pspice
Use bipolar.olb from above location.
