Verilog 12 : Continuous Assignment Statements in Verilog
Continuous Assignment Statements in Verilog In Verilog, continuous assignment statements are used to drive nets (such as wire ). They continuously evaluate the expression on the right-hand side and update the net whenever any input signal changes. These statements are commonly used in combinational circuits , bus systems , and Tri-State buffer designs . Unlike procedural assignments (which execute sequentially inside always or initial blocks), continuous assignments operate concurrently —they always stay active. 🔹 Key Characteristics Continuous assignments drive wire nets directly. Typically used for combinational logic and Tri-State modeling . Declared outside procedural blocks ( always , initial ). They override procedural assignments to the same net. The LHS (left-hand side) must always be a net type , such as wire . Can include delay and drive strength specifications. 🧩 Syntax assign (drive_strength) #(delay) net_name = expression; d...
