Quartus switch to keep all logic

I am trying to compile a very large design block per block, the complete design will not fit in one FPGA .

Is there a way:

1. To tell Quartus not to remove any logic even if inputs are floating and outputs have no loads?

2. To load the complete design and tell Quartus to synthesize it irrespective of the size?

Thanks

    If your design is too large to fit into the selected FPGA, synthethizing it block by block won't help you. You need to

    a) optimize you design

    b) try a better tool (ie, Synplify)

    c) get a bigger FPGA

    If you're just trying to synthetize each block to understand how many resources and why it's taking, just set each block as top level and synthetize the design.
