Function emit_nexys_state_soc 

pub fn emit_nexys_state_soc() -> String

The FLASHABLE state SoC (nexys_state_soc) for the Nexys A7-100T: a baked-in (a,b,c) vector ROM drives state_<name> — pulse the datapath reset, wait done (counting the multi-cycle latency), capture the result, and stream the 12-byte record {0xA5, vec, result[63:0] MSB-first, cycles[15:0]} out the UART TX, looping forever so a host can frame-lock at any time. 100 MHz; 8N1 115200 (CLKS_PER_BIT=868).
