    Dynamic Shape relief Reply

    I have probably 50 dynamic shapes on my current design and a handful of them are being problematic. I am running ver. 15.2 s068 on Windows XP. The problem that I am seeing is that I get all the Shapes laid down perfectly with no DRC errors, then I will update my silkscreen or some other non-related task and come back to find that I have 20 shape errors. I have my DRC set to 5 mil backoff from all shapes. The errors all report I have 4.99 mils clearance and the DRC value is set to 5 mils. I have to go back manually and update each shape to clear the error. There has to be a better way!

    I would recommend disabling your dynamic shape fill mode until you are done (Setup > Drawing Options > Status tab).

    Also, you could try adding a small oversize value. See SourceLink Solution 11104124; title: P-S DRC error after my dynamic shape voids the pins and vias.

    Hope this helps.

    Adding a little bit of overage in my Via to Shape backoff has worked, but it seems like a very odd workaround. I will continue to figure this out.

    IMHO: Cadence _could_ add a "Regenerate" button in the shape menu. It is a bit cumbersome to turn off and on shapes just to get a shape regeneration...

    I agree, but did you know you can do this under Setup > Drawing Options, by selecting the "Update to Smooth" button? There is an enhancement request submitted asking for the ability to update a single dynamic shape from the shape menu so you don't have to move a component 'ix 0' to update the single shape. Hope this helps!

    Isn't it totally weird to have to update your Shape from the Setup Menu? Why not put Update Shapes on the Shape menu where 99% of population would think to look for it??
