Synthesizing SystemVerilog with Yosys on WSL
From Code to Gates: Synthesizing SystemVerilog with Yosys on WSL Welcome back to AppliedKaos ! In our previous guide, we dipped our toes into the world of low-latency FPGA design by writing and simulating a SystemVerilog glitch filter using Icarus Verilog and GTKWave. Simulation is great for proving your logic works in a perfect, virtual environment. But an FPGA isn't a virtual machine—it's physical silicon. Today, we take the crucial next step: Synthesis . We are going to transform our human-readable SystemVerilog code into a netlist of actual digital hardware components (logic gates, multiplexers, and flip-flops) using Yosys , the powerhouse of the open-source FPGA toolchain. What is Logic Synthesis? If Icarus Verilog is a "debugger," Yosys is the "compiler." In the software world, a compiler translates C++ or Python into machine code (1s and 0s) that a CPU executes sequentially. In the hardware world, a synthesizer translates Hardware Description Langua...
