sroute + open nets + warnings

Hi all,

I am trying to route the followpin after the addstripe without stdcell placement.I have macro block with powerring. 

The sroute the followpins are generated well, but  for one of the memory cell, the vdd! of the followpin is open and does not extends until the power of the memory block.  I tried most of the options I knew, but couldnt succeed.

 I use these options:

 sroute -connect { corePin floatingStripe } -layerChangeRange { M1 M5 } \
-connectAlignedBlockAndPadPin { blockPinAsTarget } -blockPinTarget { nearestRingStripe } -checkAlignedSecondaryPin 1  \
-allowJogging 1 -crossoverViaBottomLayer M1 -allowLayerChange 1 \
-targetViaTopLayer M5 -crossoverViaTopLayer M5 -targetViaBottomLayer M1 \
-nets { gnd! vdd! }

sroute completes with following warnings:

 **WARN: (ENCSR-1253):   Net vdd! does not have standard cells to be routed. Please check net list.
**WARN: (ENCSR-1253):   Net gnd! does not have standard cells to be routed. Please check net list.
