This work presents a fully digital and synthesizable LNA Synthesis Engine that translates traditional analog amplifier design into a hardware-driven evaluation and optimization process. Implemented entirely in Verilog, the engine replaces conventional SPICE-based analysis by employing ABCD matrix modeling, S-parameter transformations, and stability computation through fixed-point arithmetic. A 64-bit genome representation encodes amplifier topologies, which are evaluated in real time through a pipelined mathematical engine. The system identifies the best-performing topology using hardware-based metrics including gain (S21), input reflection (S11), noise figure (NF), and power consumption (PDC). The accompanying waveform results confirm correct genome generation, stable convergence of S-parameter calculations, deterministic selection of the highest-fitness candidate, and reliable unconditional stability detection. Integrated with open-source EDA tools such as Yosys and OpenSTA, the engine supports synthesis, timing, and power analysis, enabling a complete end-to-end design workflow. The results demonstrate that analog performance evaluation and topology optimization can be achieved directly in digital hardware, establishing a foundation for automated, hardware-aware analog design and future machine-driven RF circuit synthesis.
