(X) the output will also be unknown. Verilog will not throw an error if a vector is used as an input to the logical operator, however the code will likely not work as intended. It is recommended to first use thereduction operatoron a vector to turn it into a scalar before using a ...
If this is the first time you have looked at VHDL Code before, you should start with atutorial geared for beginners. The entity/architecture combination is the most fundamental building block in VHDL. Entities and Architectures are used together to define a piece of functionality. There should ...

In the above verilog code we have defined states by equivalent binary number through keyword parameter.In the design part we have used three always block.First always block does state change at positive edge of clock when reset is low.Second always block decides what will be the next state ...
If you have closely watched the schematics above and the verilog code below it, you must have appreciated how verilog simplifies the process of hardware design. Before the advent of Verilog, everything was done using schematics. The Schematics were error-prone, difficult to verify and had long ...
Problem - Write verilog code that has a 50 MHz clock and a reset as input. It has an output that can be called clk_out. The clk_out is also a clock that has a frequency of 2.5 Hz of time period of 400 ms. Extend the parameter to calculate the values for the parameter for 1 ...
