some strange layout error

tester

Dear All,

The DRC test has been passed with no errors. However, there are a few area still have flashing x sign. For instance, the portion of metal 1 extended from the source of PMOS, which overlaps vdd (metal 1 as well) has flashing x sign. Can anyone give me some hint please?

Thanks

  • Tester,

    I hope you don't think I'm being rude, but how do you think anyone could possibly answer your question? You didn't say:

    1. What Physical Verification Tool you're using
    2. What process/design kit you're using

    That's just the bare minimum. Ideally a picture of the problem would help. Did you use Layout XL to do the layout? Maybe there's a marker on the layout due to layout XL? Perhaps you can do Verify->Explain and click on the marker to see if there's an explanation?

    Regards,

    Andrew.
