According to the FPGA Σ-Δ D/A converter design and implementation strategies, Σ-Δ DAC' s internal only by the two 10-bit binary adder, a 10-bit latch and a D flip-flop, with the FPGA implementations consume only minimal logic resources, using the smallest FPGA can achieve. This is the Σ-Δ DAC implementation verilog language!
