DRC + ULP

autodeskguest

I want to write a ULP can cleansup board designs after the autorouter.

The first thing i want to solve is this problem:

You usually set the minimum width to the minimum of your board

manufacturer. nice for the router, but you endup with a very difficult

to produce design. i want to make a ULP that loops thrue all wires, and

makes them thicker, then runs a DRC to check for (new) errors.

 

Is this possible?

    If you are referring to the DRC setting, then yes.  Actually I usually

    default to 8 mil width with 8 mil space, then set it smaller only if I

    really need to.  Every board house I know of can do 8/8 rules and not mess

    it up.

    That's definitely not the way to do it.  It won't even work in many cases.

     

    You really need to do HELP CLASS and read it very carefully.  That's the

    right way to get what you want.
