    Hi everyone
    I am running a project that requires a rather large scale VLSI circuit design with hspice using CMOS 0.35 micron technology .l model file. I was wondering if there would be :
    1- Any ways I could import the .l hspice library into ltspice hence could run the MOSFETS with the correct specs
    2- Any ways I could make a circuit schematic using ltspice and could export the netlist to hspice format or use hspice to read and simulate the ltspice generated netlist.

    Welcome to this forum.

    1) As long as the library you use does not include HSPicespecific statements that LTSpice wouldn't recognize, you can use the HSPice libraries.
    2) In LTSpice click "view" -> "Spice netlist". LTSPice will create a text file (xxx is the name of your schematc aka xxx.asc file) in the same directory where the .asc file is located. This .net file is a standard ASCII Spice netlist. You should be able to use it in HSPice.

    See also the ressource section of this forum for more information on LTSpice.
