Errors in pad fillers using AMS 0.35u technology (SOCE)

Mooty

Hi,

I'm using SOCE for P&R and I keep getting this spacing error with the pad fillers:

Pin of Cell IN0_5 & Blockage of Cell pfill_W_44

Actual:     0.7     Min:     0.8    bbox = (180.000, 1768.250) (180.700, 1772.550)

 I cannot seem to resolve it.  What could be the problem?

  •  Hi Mooty,

    The first picture looks like nanoRoute is trying to route some nets that are really connected by abutment of the IO cells. You should place a -skip_routing attribute on these nets:

    setAttribute -net net1 -skip_routing true

    The second picture looks like a violation between the route to the IO pin and the blockages around the IO pin. These may or may not be real violations - you'll have to run your signoff DRC to be sure. 

    I'm not sure about the other two.
