Logic fabric and memory budget
The LFCPNX-50-7ASG256I packs 52000 logic elements and 13000 LAB/CLB blocks. That is a mid-density sweet spot — big enough for a soft-core processor plus a few DSP accelerators, but not so large that the 256-ball package starves the core of I/Os. Count the LUTs honestly: if your design synthesises to 42000 LUTs, you have 19 % fabric margin before you start fighting placement. On-chip block RAM totals 1769472 bits.
