Predictable Hardware Design with Synthesis-Oriented RTL
Build synthesizable Verilog RTL that maps predictably into hardware. Apply correct combinational, sequential, latch, and three-state modeling patterns, with disciplined assignment styles, reset coding, synthesis attributes, and construct restrictions to avoid unintended inference and simulation-synthesis mismatches.

Description
Synthesis-oriented RTL design focuses on the connection between Verilog source code and the hardware inferred by synthesis tools. Procedural blocks, continuous assignments, sensitivity lists, event controls, conditional branches, and assignment operators are interpreted as concrete circuit structures. Accurate RTL must describe functional behavior and hardware intent at the same time, so the generated netlist matches the simulated model. Combinational logic modeling depends on complete sensitivity and complete assignment. Every input used in a calculation must trigger reevaluation, and every output must receive a value on every possible path. Correct sensitivity lists, always @*, default assignments, complete if and case structures, blocking assignments, and continuous assignments help describe pure combinational behavior. These patterns prevent accidental latch inference and reduce mismatches between RTL simulation and synthesized logic. Sequential logic modeling requires precise event control, reset handling, and assignment discipline. Edge-qualified clock events define register inference. Synchronous and asynchronous resets must be written according to their true hardware beha...
