Ways to speed up compilation on a large model

[mfkasim1]

I have a computer-generated Verilog-A file that has 517 electrical nodes (5 of them are inout), 2880 real variables, and it's taking a very long time to compile (it's >30 minutes now and it's still compiling). Here's an example of my file (cut down due to size):

module mymodule(p1, p2, p3, p4, gnd);
    electrical p1, p2, p3, p4, gnd;
    electrical e0, e1, ...;  // there are 512 electrical nodes here
    inout p1, p2, p3, p4, gnd;
    parameter real ccc = 1p from (0:inf);
    real var0, var1, var2, ...;  // there are 2880 variables here
    analog
    begin
      ...  // the main body has 256 ddt
    end
endmodule

Do you have any suggestions on how to speed up the compilation?
