THe SB_DFFESR module is a D flipflop ... especially if you look at the output Verilog code, too. The topmost LUT is the XOR gate, while the bottom one is an OR gate that feeds the flip flop ...

so we can use strange Verilog features that we don’t normally use in our regular code. The first thing to do is create a module for the testbench (the name isn’t important) and create an ...

Here is an example of one-hot assertion checking logic included in the Verilog code. Even this simple assertion raises several issues. Two new variables (ones_found and idx) have been added to the ...

In Verilog programs, modules are the object types that are created by the designer to model a hardware device. Modules instantiate other modules and include code of their own to describe the device ...

for hardware design and verification and a provider of platform-independent software tools for efficient code development, today announced the release of the DVT Debugger Add-On Module for the e ...

Also unresolved in March was the proposal to allow SystemVerilog users to instantiate modules with implicitly named ports. That proposal was passed by Accellera. “It simplifies quite a bit of Verilog ...

For some piece of code which is common and frequently used in different and completely isolated modules, the function/task can’t ... There are many other cases where we see code duplication. “System ...

This paper focuses on the implementation and simulation of 4-bit, 8-bit and 16-bit carry look-ahead adder based on Verilog code and compared for their performance in Xilinx. Catch up on the latest ...
