You don’t usually think of simulating Verilog code — usually for an FPGA — as a visual process. You write a test script colloquially known as a test bench and run your simulation.… ...

So the code instructs the FPGA (or, more accurately, the Verilog compiler) to examine the number and set dispoutput based on the input. The <= character, by the way, are a non-blocking assignment.

Sometimes good ideas take a while to catch on in engineering practice. The use of in-line assertions to document assumptions and check for problems in RTL code is one such idea. Long ago proposed for ...

Icarus Verilog also includes a unique feature not available to other Verilog compilers: the loadable target API. This is a C API for loadable modules that the compiler can invoke to generate output in ...

To take a simple example, if a task-function has common code for two different monitors and for two different interfaces, a DV engineer mostly adds duplicate code in both the monitors. There are many ...

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.

However, this also increases complexity of using processes in System Verilog. What makes it tricky is process usage in the context of object oriented programming. I know that sounds counter intuitive.

Today, Dekker and a team of dedicated engineers develop parsers and elaborators for SystemVerilog, Verilog, and VHDL that have been used as the front-end software for synthesis, simulation, formal ...
