Overmapped error in FPGA

Hi
I am using NI PXI 7831-R RIO card and the LabVIEW FPGA module.
I have an application that implements serial protocol for reading and writing to the COM port of the computer.
I have developed the FPGA VI and when i try to compile the same, i am getting
"Overmapped Error: ERROR:Pack:18 - The design is too large for the given device and package"

It would be of great help if somebody could help me to optimize the design and solve this issue. Also is there any way to know the size in terms of number of logic cells or logical slices taken by each loops, cases, arrays, local variables, FPGA functions and arithmetic & logical functions?

Thanks and regards
