Hi Sebastián, Unfortunately, the issue is exactly as reported: The design is too big to fit on the device.
In your case, you are running out of soft logic -- that is, you're running out of the FPGA's general purpose "SLICE" logic. It's possible your design just has too much going on, and you'll need to remove some of its functionality. More optimistically, it's possible that you have some particular problematic piece of logic using lots of registers, which could either be more efficiently implemented or tweaked so as to take advantage of other FPGA resources you're not using, like DSP slices or BRAMs. Since you mentioned you solved a timing problem before hitting this error, I'm wondering if you did something to help timing such as cranking up the latency on some pipelined bit of logic -- such as cast blocks in the FFT -- which has caused an explosion in register use.
