I need some help. I have been trying to create a library file with different biased ideal opamps. Looks like this:
.subckt Ideal_OPAMP v_plus v_minus v_out
*
*This is an ideal OPAMP model with the output voltage
*limited to +/- 15V
*
Rin v_plus v_minus 10MEG
Eamp v_out 0 value={LIMIT(1MEG*v(v_plus v_minus), -15, 15)}
R0 v_out 0 10MEG
.ENDS
I change the power supplies and rename the part. This one would be Ideal_OPAMP_15. How do I go about this? I would like a library that would have the basically the same SUBCKT but with the power supply values changed the name changed.
I will tell you what I have done.
1). I create a .lib file with the above SUBCKT.
2). I open the file in the Model Editior.
3). I click on Model->Copy From ->
4) Label the next one Ideal_OPAMP_20
5). Choose Ideal_OPAMP in the copy from box. Click on OK
6). After several new OPAMPS are created I then choose File->Model Import Wizard-> and run through the options.
7). Save it
8). Open Orcad and create a new project.
9). Load the part library.
This is where my problems exisits. Under the library where I have save the parts I only get one part. Not the 5 or 6 I have created.
Any ideas?
