I am trying to simulate a circuit which its main components are LTC3105 and LTC4070 using Proteus 8.. Can any body advice me how to add them to the library?
I think spice simulation is not possible to do with LTC devices in Proteus. Linear Tech doesn't support macro file, you only can use LT spice for simulation.
you must made a new library by design schematic of LTCxxxx in proteus that you have need them. then added that library on the list of library of proteus and for the next time using them.
