Rules file must contain a CAPACITANE ORDER statement.

i m new in 65nm and i need to do layout of my circuit in 65nm. kindly help me.

PEX differentiates between several types of capacitances: lumped (discrete, planned) capacitors, device input & output capacitances, and parasitic capacitances (which it extracts). From LVS comparison it recognizes the former types, from its own function it knows the parasitics. But then it's necessary to know how it should treat these different types of capacitances, and in which order. That's why the rules file needs rules how to assign the different cap types, and in which order this should be done: this needs the CAPACITANCE ORDER statement.

The corresponding foundry supported rules file should have this ORDER STATEMENT. Perhaps you used the wrong rules file?
