Design data often has logical groups of signals, such as all the control signals for a bus protocol, or all the signals used within a state controller. The Verilog language does not have a convenient mechanism for collecting common signals into a group. Instead, designers must use ad-hoc gro...

// Logical Operators (return boolean values) assign logic_and = a && b; // Logical AND assign logic_or = a || b; // Logical OR assign logic_not = !a; // Logical NOT// Comparison Operators assign eq = (a == b); // Equal assign neq = (a != b); // Not equal assign ...
Numeric Instructions: These instructions perform arithmetic, logical, and comparison operations on the basic data types. They include both unary and binary operators, such as addition and subtraction. Parametric Instructions: These instructions operate independently of specific data types and primarily facili...
