    Hi,
    I'm trying to learn how to properly use most of Altium Designer functions. Through the design part of my project (Gamma PIN detector) I've come across an obstacle, that there are no SIM models for parts in the project schematic sheet. There are 3 more parts that need their model:

    1.Voltage regulator LM1117-5.0
    There is unencrypted PSpice library on mouser (https://pl.mouser.com/ProductDetail...117IMP-50-NOPB/?qs=X1J7HmVL2ZHO6cZ9lqve%2bA==) but after some attempts to add the model in the part properties I've no idea how to make it work for me (it keeps on telling me that such model does not exist)

    2.Then there are photodiodes BPW34. I've also found some kind of spice model for those parts:

    *****************************************************************

    **** F301 SENS=100 at 880nm, BPW34,BPX61,SFH205,206,235, lens=1
    .subckt BPW34 Opt_In+ Opt_In- Cath Ano
    +params: SENS=100 resp=50e-5 lens=1
    G001 2 Ano Opt_In+ Opt_In- {SENS*resp*lens}
    D1 Ano 2 F301
    Rs 2 Cath 6.5
    .model F301 D(IS=3.5e-11 N=1.01 IKF=6e-5 Cjo=73.01p M=0.452 Vj=0.304 BV=200)
    .ends

    But, the way to implement it to Altium SIM model is unknown to me...


    3. The worst case of all I think is the LTC6269 or 6268 (amplifier). The model for this part is nowhere to be found exept for the LTSpice library itself. I have used it in previous simulations with the old LTspice, and guessing by that i should be able to export the library easily to Altium, but apart from the symbol the .sub file does not exist! All the other parts have their subcircuit files but for this I cannot find. Is it somehow hidden or replaced by op amp with the same properties?

    I 've tried to look for some tutorials/courses/solutions to those cases but rarely found anything useful...
    Please help.

    Hi

    Its located in LTC2.lib and uses the LTC6268 model

    You can not use this model. it uses the specific LTspice syntax.

    Thanks for advice. I'm afraid that those companies have locked their models for own software and it's awful not to be able to simulate everything in Altium. (it would have been a lot easier, but noooo.....) So temporarly I give up on the altium sim for the sake of the project and switch to LT Spice where most of the models are. (but it has enormous problems with some more complicated/especially imported models).
