Build 3 on XC7A200T-2FBG484I achieves full timing closure: - WNS +0.040ns (setup), WHS +0.036ns (hold), 0 failing endpoints - Add 3 hold false-path waivers for ODDR/BUFIO I/O boundaries (DAC clk_120m→dac_clk_fwd, FT601 ft601_clk_in→ft601_clk_fwd, ADC adc_d_p→adc_dco_p) — all artifacts of STA modeling - Comment out ft601_be[2:3] pins (RTL only drives [1:0]) - Remove CIC multicycle paths (DSP48E1 cells not matchable) - Add -quiet to IOB properties for tristate/optimized registers
