aoc: First stage compilation completed successfully.

Compiling for FPGA. This process may take a long time, please be patient.

Error (170012): Fitter requires 5692 LABs to implement the design, but the device contains only 4191 LABs

    Hi,

    Based on my knowledge, you may need to remove some logics to optimize and fit your design.

    Is there any other error during your compilation?
