We can express this data as either a binary, hexadecimal or octal bit is a 2-state System Verilog variable (0, 1) that cannot represent unknown or high-impedance states and is commonly used in testbenches for faster and By default byte, shortint, int, integer and longint default to signed and bit, reg, logic, and wire defaults to unsigned. $bits system function returns the number of bits required to hold an expression as a bit stream. Since you tagged Verilog I’ll assume you want to know that behavior. Verilog has reg and wire data-types to describe hardware behavior. 5. One moment, please Please wait while your request is being verified 3) reg, always Including all inputs in the sensitivity list can be tedious and prone to errors especially as the number of statements in the always block grows always @(sensitivity list) begin statements end Verilog’s variable types are four-state: each bit is 0,1,X or Z. Learn how to represent numbers in Verilog, the syntax for specifying bit-widths and bases, and best practices for using constants in digital design and simulation.
