An important warning confused me--tri-state nodes do not directly drive top-level

Hello,

I dont know if this the right place to this quetion, but some one know how obtain the capacitance of instances in a netlist file from Quartus II tool.

I need to use the netlist file from Quartus tool, in the Nanosim tool from Synopsys, because there isn't any Altera tool to obtain the capacitance of a instance (resistor, transistor, capacitor, etc) of a FPGA design.

Thank you for help.
