If this is the first time you have looked at Verilog Code before, you should start with a tutorial geared for beginners.always_block.v:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 // Create...
The Verilog replication operator is the open and close brackets {, }. It should be mentioned that these brackets can also be used to do concatenation in Verilog, but that is for another example. The replication operator is used to replicate a group of bits n times....
Example code of using function to build SystemVerilog Coverpoints and Cross bins I have CoverPoints that are over enumerated types and I want to limit the number of bins to be subset of the values. This is done so that I have limited the number of bins goi...
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 ...
Often a function is created when the same operation is done over and over throughout Verilog code. Rather than rewriting code, one can just call the function. This prevents copy and paste errors and allows for more maintainable code: if the behavior of the function changes, it only needs ...
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 ...

They operate on all of the bits in a vector to convert the answer to a single bit. The logic performed on the bit-vectors behaves the same way that normal AND, NAND, OR, NOR, XOR, and XNOR Gates behave inside of an FPGA. The code below demonstrates the usage of the Verilog ...
