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?

  •  For the first issue, if you mean that the IO ring is connected by abutment but you are seeing violations, it could be blockages causing verify geometry to think there is an error where there really isn't. You can try turning on/off some of the ver geom settings and see if you get different results. The real test is signoff DRC. Does it show any problems in your IO ring?

    For the second issue, it's hard to tell from this picture (not everything is turned on), but it looks like you have a wide metal (the power) too close to regular routing. Maybe your clock routes are double-width? I'm not sure. Turn on signal routing and see if you can tell what the error marker is flagging. The text description should also shed some light.
