micheleandClaude Sonnet 5 ffc1c7ccfc docs: reflect flash #1 removal and the N=4 8/8 timing recovery
Datasheet and pinouts.md updated to the current, real state after
today's session: flash #1 was implemented then removed (user's own
MHz-over-persistence priority call), the clock-closure table now
shows the post-revert, post-DEC-0042 numbers (N_SLOTS=4 @ 64MHz 8/8,
worst 64.55MHz/best 72.37MHz; N_SLOTS=8 deferred by explicit user
request), and the FPGA_DATA_READY any_pending formula is updated to
the real counter-based implementation (credited to the user's own
diagnosis) that fixed the last failing N=4 seed.

Compiled clean (45 pages, 0 errors).

FPGA-Neural — Datasheet

Datasheet tecnico multicapitolo dell'engine FPGA-Neural, in italiano e inglese. Ricostruito a partire dal codice RTL, dalla documentazione e dai benchmark presenti nella repository (revisione A1, settembre 2026).

Nota sul pinout

Il capitolo Progetto hardware e mappa dei segnali riporta l'analisi completa segnale-per-segnale del top-level spi_neuron_top, con la colonna Ball compilata con assegnazioni CABGA381 reali (53 segnali, .lpf reale in synth/) e verificata da un place&route reale (nextpnr-ecp5, 0 errori di vincolo, Program finished normally) — non più auto-piazzate.
