micheleandClaude Sonnet 5 ff5908f25f docs: log DEC-0009 -- project v22 paused, hard DSP resource ceiling on ECP5
Real nextpnr-ecp5 resource data shows the ECP5 family (45F: 72
MULT18X18D, 85F: 156) cannot reach the 20x-1000x speedup targets
discussed today with this or any redesigned architecture -- N=16 was
already near the 85F's absolute physical ceiling of 19 cores. User
made an informed decision to pause the project rather than chase a
target this hardware family cannot physically deliver.
