T Flip Flop T stands for (“toggle”) flip-flop to avoid an intermediate state in SR flip-flop. We should provide only one input…

Verilog Control Blocks Hardware behavior cannot be implemented without conditional statements and other ways to control the flow of logic. Verilog has…

Verilog Johnson Counter A Johnson counter is a digital circuit with a series of flip flops connected in a feedback manner. Verilog…

Verilog Task A function is meant to do some processing on the input and return a single value. In contrast, a task…

D Flip-Flop A D flip-flop is a sequential element that follows the input pin d at the clock’s given edge. D flip-flop…

Lexical Tokens Lexical conventions in Verilog are similar to the C programming language. Verilog language source text files are a stream of…

Verilog Timeformat Verilog timescale directive specifies time unit and precision for simulations. Verilog $timeformat system function specifies %t format specifier reporting style…

Verilog D Latch A flip-flop captures data at its input at the negative or positive edge of a clock. The important thing…

Verilog Mod-N Counter Counters are sequential logic devices that follow a predetermined sequence of counting states triggered by an external clock (CLK)…

Verilog Timescale Verilog simulation depends on how time is defined because the simulator needs to know what a #1 means in terms…
