Re: [Help-gnucap] spice models

[Mogliii]

OK, I got a bit closer to my aim.

I found this very helpful page: http://www.brorson.com/gEDA/SPICE/t1.html

Following this I made the following schematic:
http://users.ecs.soton.ac.uk/mets09r/test3.sch

I copied the spice model I found here [1] into a subckt file
http://users.ecs.soton.ac.uk/mets09r/LM317.subckt
and gave the LM317 the following attributes:
    device = LM317            (apparently not necessary)
    refdes = U1
    value = LM317             (exactly the same as the .SUBCKT LM317 1 
2 3 in spice file)
    file = LM317.subckt     (file with spice model is located in same 
directory as sch file)

Now when I load it in gspiceui the netlist finds the spicefile and 
netlists all. But when I do the simulation I get the following console 
output:

The J1 seems to be the problem?

Now my questions:
    1) Do I have to rewrite the spice model to work with gnucap?
    2) gEDA includes the LM317 as symbol, but apparently no spice 
model? Is this correct?


I appreciate your help in advance
