Danglling wires after LVS

ssuhas

Hi,

For my block level design I am getting danglling wires after doing verify connectivity.

I am getting these errors at the end of all standard cell rails.

What is the reason for the error and how do we debug it?

 Thanks

    I would suggest adding end cap cells at the end of core rows using

     addEndCap
    [-help]
    -preCap cellName
    -postCap cellName
    [-prefix prefixName]
    [-coreBoundaryOnly]
    [-flipY]
    [-powerDomain powerDomainName]
    [-area x1 y1 x2 y2]

    End-cap cells are preplaced physical-only cells that are required to meet certain design rules.
    They are placed at the ends of the site rows. 

    See if it fix your issue.
