nx_jtag_load.nx

nx_jtag_load.nx -- LIB: JTAG bitstream LOADER (omniforge SI M5 = the OpenOCD replacement, sim). Models the REAL IEEE 1149.1 TAP state machine (16 states, TMS-driven) and loads a bitstream into a config Data Register via Shift-DR -> Update-DR -- exactly how OpenOCD drives an FPGA. The twin property: the bits shifted in arrive in config faithfully, and the configured fabric runs the design. never-brick #26: VOLATILE config (an SRAM model, no persistent/flash write -> a power cycle clears it, can't brick BY CONSTRUCTION), bounded, deterministic. license_tier: ORIGINAL
