Verilog Multiplexer A multiplexer is a device that selects one output from multiple inputs. It is also known as a data selector.…

Gate Level Modeling In Verilog, most of the digital designs are done at a higher level of abstraction like RTL. However, it…

Verilog Scalar and Vector Verilog needs to represent individual bits as well as groups of bits. A single bit sequential element is…

Verilog Gray Counter Gray code is a kind of binary number system where only one bit will change at a time. Today…

Verilog Scheduling Semantics Verilog design and testbench typically have many code lines comprising of always or initial blocks, continuous assignments, and other…

Verilog Initial Block The always block indicates a free-running process, but the initial block indicates a process executes exactly once. Both constructs…
