14.5. Introduction to Multiway Branching
Multiway branching allows HDL code to make decisions and execute different code paths based on conditions. It is fundamental for implementing control logic, state machines, decoders, multiplexers, and complex decision-making circuits.
What is Multiway Branching?
Multiway branching provides mechanisms to choose between multiple execution paths based on conditional expressions. Verilog offers two primary constructs:
-
if/else Statements - Priority-based conditional execution
-
case Statements - Parallel multi-way selection
Where Are They Used?

Synthesizability
IMPORTANT: Both if/else and case statements are SYNTHESIZABLE when used correctly in always blocks. They generate combinational or sequential logic depending on context.
