    General Clearance Rules - copper to outline

    radek

      Hi colleagues,

      I am trying to specify design rules with Constraint manager, general clearance rules like copper (poured copper) to board outline but I am unable to find any setting like this. I found General Clearance Rules dialog which I suppose I need to use to set this kind of rules. Like on documentation on supportnet:   https://supportnet.mentor.com/docs/201303047/docs/htmldocs/mgchelp.htm#context=ces_user&href=chapter308.html&single=true

       

      It contains only one rule for placement outline to placement outline.

       

      Where can I specify other rules like copper pour to board outline?

       

      Thanks for any help

      Radek

          Hi Radek,

          I think you use PADS flow, not Xpedition flow. If you look first page of link you sent, "Software Version EE 7.9.5" was seen. So this manual belongs to xPedition flow Constraint Editor System, not PADS. You can find manuals belong your tools clicking PADS Layout>Help>Documentation window> "Constraint Manager user's Manual". Or same document available in your Supportnet PADS Layout web page >Reference>Product Docs section as following link.

           

          Constraint Manager User’s Manual (Software Version PADS VX.1.2) > Specifying General Clearance Rules:

          https://supportnet.mentor.com/docs/201507074/docs/htmldocs/mgchelp.htm#context=ces_user&id=83&tag=92859

           

          If you are old PADS netlist flow user and now starting to use PADS Integrated flow, you can see match explanation between both flows rules system:

          Netlist Project to Integrated Project Migration Guide > Rules Differences and Migration:

          https://supportnet.mentor.com/docs/201504002/docs/htmldocs/mgchelp.htm#context=net2int_user&href=rules1.html&single=true

           

          As you can read in that link, old copper to copper clearance is trace to trace clearance anymore. Old Board to Copper clearance is a general setting under Tools>options>Routing>General>Board Outline Standoff.

          Netlis Flow                                                                                                     Integrated Flow

          Copper to [Trace | Via | Pad | SMD I Copper]

          Trace to [Trace | Via | Pad | SMD | Trace] clearances are used.

          Board to [Trace | Via | Pad | SMD I Copper]

          This is a single global clearance in Options.

           

          Hope it helps,

          Hande
