Netname problem

banker

when I do the layout for dicecell ,I add metal1 pin on vdd,Then I find all the netnames  of metal1 dg on my layout is vdd!, so I couldnt add pin of gnd,cause it said it has short with vdd,so how can I do for this situation

  •  Hello Mr. Banker,

     you probably have a short somewhere in your layout. If it is a small cell you might be able to spot
    it manually. If it is a large block things get more difficoult. I don't know what verification tool you are using
    but most have some kind of short detector tool. The  one in Assura works well and is easy to use.

    Kind regards,

    Marc
