Verilog 16: Complete Guide to Logic Synthesis
1. Introduction to Logic Synthesis Logic synthesis is the process of converting high-level hardware descriptions into gate-level implementations that can be physically realized on silicon (ASICs) or programmable devices (FPGAs). In simpler words: Logic synthesis translates your Verilog or VHDL code into a network of logic gates and flip-flops that can be physically built. 1.1. Life Before HDL and Synthesis Before hardware description languages (HDL) like Verilog: Engineers manually designed circuits using logic diagrams or schematics . Large designs were error-prone, difficult to modify, and time-consuming to implement. Optimizing gate count or timing was extremely hard. Challenges: Reusing a module in multiple projects was labor-intensive. Making changes in design required redrawing entire schematics. Verification and debugging were manual and slow. 1.2. Impact of HDL and Logic Synthesis With HDL and synthesis: Designers write behavioral or stru...
