Sroute not connecting pads

Hello,

I am using command      sroute -connect { padPin padRing } -layerChangeRange { M1(1) LB(9) } -blockPinTarget { nearestTarget } -padPinPortConnect { allPort oneGeom } -padPinTarget { nearestTarget } -corePinCheckStdcellGeoms -allowJogging 1 -crossoverViaLayerRange { M1(1) LB(9) } -area { 1076.874 1428.067 1190.36 1216.186 } -nets { VDD_CORE GNDS_CORE } -allowLayerChange 1 -targetViaLayerRange { M1(1) LB(9) }

 However , The VDD_CORE and GNDS_CORE nets are not connected to respective pads.

I also get warning:

**WARN: (IMPSR-1254): Cannot find any block pin of net VDD_CORE. Check netlist, or change option to include the pin.

VDD_CORE is definately in the netlist
