How can I use a .lib in MWO to generate a schematic ?

Hi....

I need to use the file with extension *.lib in MWO to generate a schematic and make some simulations, I followed these steps:

Circuit Schematics->Import Netlist to load the file, but when I search in subcircuits and try to put it in there, I get the message "bcr400 has no ports".

Thanks a lot for your help....

Hello Luis,


just change this file extension as *.cir (PSpice format) & then import it as PSpice netlist it works fine....
If still have issues, append the file here...

Hi Manju...

Thank you for your help, I changed the extension and imported it, but MWO show me some errors, I attached here the errors and the *.lib so you can give me a hand again, in this moment I have the subcircuirt but I'm not sure if that block is working.

Hello Luisfe,

I had a look at this .lib file the it contains three subcircuits for Q, D, & R (BJT, Diode, & Resistor) then in top level code are connected...
You need to have separate Spice files for each subcircit say "Q1.cir"

& then import to MWO...

or edit the .lib file to compatible PSpice hierarchy to support subcircuit format see the pscie format documet....
