Dear All,

I am designing a digital small chip using Mentor Graphic IC Station tools.
I have finished all steps but I have LVS ERROR in the final. which states as:

Error: Different numbers of ports (see below).
Error: Power net missing in layout. Ground net missing in layout.

Although I have NOT these errors when I made the LVS check for the die before adding IO Pads.
The LVS report for the Die with and without PADs are attached.

I solved the problem by adding an extra port(Add->make-> port) in the final layout(Although this ports are existing in the die layout) but Calibar can't recognize it.
