Parasitic capacitance extraction problem

Hi, dear all,

I was using Calibre xrc 2010 version. There is a long metal wire in the circuit, which was extracted as distribued resistances along the wire and a big lumped capacitance at the end node of the wire. Shouldn't the result be distribued r and c? I used rc and rcc options which returned the same model type for the wire.

I checked the rule deck, there is no reduce option specified. and I used report distributed option.

Any suggestion will help. Thanks a lot.
