Restriction of autorouter?

Former Member

Hi,

 

I'm still pretty new to Eagle. I've made a few PCB's so far, and they've

turned out great, but I hadn't used the autoroute function at all until

now. I need some advice.

 

I've already routed a particular area of the board since it is a

measurement circuitry area. However, now that I want to route all of the

digital signals, is there a way to restrict the autorouter such that it

does not mess with my already routed measurement circuitry?

 

Regards,

Brian

    Olin,

     

    Yes, that's well and good to look in the help, except that I don't find

     

    the help article on this particularly helpful. What is the purpose of

    specifying net classes? What are they used for?

     

     

    As Doug already mentioned, they are used by the DRC and auto-router.

     

    For more info about the auto-router see the online help for the "auto"

    command.  You can have it route a list of signals only.  But you can't give

    it a net class to complete, although I agree that could be useful.

     

    Also take a look at the auto-router section of the manual.  There is some

    useful info in there.  If you don't have a printed manual there is a copy

    in the /doc of the install directory.

     

    Cheers,

     

    James.
