    Hatch width in Expedition

    Arunraj

      Hi All,

       

      Is there any possibility to create to different hatch width for a net?

       

      What I meant to say is, for constraint area or rule area I need minimum hatch width and in the master area or other area I need some more hatch width.

          Is this what you mean? Shown are Default (solid), Hatch and Hatch2.

            Not exactly..

             

            I want two different hatch widths for a net (same net) at two different region with 100% metal

             

            For example,

             

            I have minimum rule area (minimum DRC's) and remaining areas are master area (maximum DRC's)., In the minimum rule area I want to make hatch width as minimum (5 mils) and in the master area it should be more (10 mils)

             

            All these things I want to do to make better DFM. Hope I explained correctly or else let me know

              These are the same net and use a different hatch width. The left has Plane Class of Hatch1 (.025) and the other one is Plane Class Hatch2 (.005), both are GND.

              Is that what you mean?

                You made it with two different shapes for same net.. I want to make it with single plane shape which should discover .005 (hatch 2 ) in minimum rule area and .025 (Hatch1) in master area.

                 

                I don't want to make two plane shapes for same net. Its a tedious progress of placing two shapes where i have Lots of power at the DUT and the device is .35 mm pitch with flip drill technology.
