LVS Fails, after P&R extra pins in layout

Hello all

 

When runing LVS with Calibre, it fails because the layout has more pins than the schematic. Digging into it, it turned out that when streaming in the gds file generated by encounter I got labels in the internal nets. If I remove those labels, then the issue is solved.

 

I wonder what should I setup to avoid those labels in the internal nets? I have been stearing at the streamout.map file, the cds2gds.map and the technology file, but can't find anything that ring any bell.

Finally, we used to work with IC51 and now we are working in IC61. Does that make any difference? 

 

Thanks!
