When using model editor to export a TI LMH6629 SPICE model, I get:
STATUS: PSpice Schematics to Capture translator (16.6.0.d001)STATUS: STATUS: Translator started at Thursday, October 03, 2013 16:31:52STATUS: C:\Cadence\SPB_16.6\tools\Capture\sch2cap -f INFO(ORSCH-1029): Using existing library
ERROR: [S2C3471] Base part library does not exist
STATUS: Translator stopped at Thursday, October 03, 2013 16:31:53STATUS: 1 Error messages, 0 Warning messages
Which, from my interpretation, tells me Model Editor cannot find the models in my text file:
.MODEL QDP PNP
.MODEL QDN NPN
.MODEL QON NPN VAF=150 BF=420 IKF=1.5 RE=0.5 RC=1
.MODEL QOP PNP VAF=150 BF=420 IKF=1.5 RE=0.5 RC=1
.MODEL QIP PNP VAF=150 BF=260 IKF=0.005 RB=1.4 RE=0.1 RC=1
.MODEL DVN D KF=4E-13
.MODEL DIN D KF=26E-14
.MODEL DIC D RS=0.1
.MODEL DD D
.MODEL PSW PMOS KP=200U VTO=-7.5 IS=1E-18
.MODEL NSW NMOS KP=200U VTO=7.5 IS=1E-18
.MODEL QSW NPN
.MODEL NEN NMOS KP=200U VTO=0.5 IS=1E-18
Where are the NPN, PNP, D, NMOS, etc models located? In what .lib file? I have searched through the SPB_16.6 PSPICE libraries and cannot find them. Thanks.
Your goal is not clear. What exactly are you trying to accomplish? Commend mentioned by you would generate the symbol library. These symbols are used to create schematic/designs. Is this the goal? Why? Since you installation already has symbol libraries for all models shipped with it.
Are you using licensed version or Lite (Demo ) version ? Note that Lite version support limited capabilities?
Answer to these questions would help others in providing exact input.
In reply to alokt:
Thank-you for the response.
The goal is to export the TI OpAmp PSPICE file to a .lib file for use in a simulation. The licensed version of SPB 16.6 does not have a model for the LMH6629. The error shown seems to indicate Model Editor cannot find the files for Models NPN, PNP, D, PMOS, NMOS, however, I am not 100% certain, and I do not know what .LIB file the NPN, PNP, D, PMOS, NMOS models are kept.
