Constant THREE_LANE_PROJECTED_ARCHITECTURAL_REGISTER_BITS 

pub const THREE_LANE_PROJECTED_ARCHITECTURAL_REGISTER_BITS: usize = _; // 154_578usize

Total projected architectural register bits in the full farm.

This is the arithmetic sum of the pipeline, pointer, and registered-memory output fields authored in RHDL. It must not be reported as FPGA utilization.
