![]() HDLs alone were not sufficient to reduce the workload on VLSI circuit designers. ![]() It is assumed that the readers have some basic knowledge in Verilog programming. In this article, I will introduce you to an open source Verilog simulation and synthesiser tool. That’s how hardware description languages (HDL) came into being. In the 1980s, designers felt the need for a language that could model digital circuits so that the circuit could be simulated and analysed. Today’s integrated circuits are so complex that they contain thousands of transistors on a single chip. Gone are the days when designers could verify their circuits on a breadboard. This is the trend not only in electronics but in all spheres of engineering. The complexity of structures is so high that we can no longer think about doing things manually. It can also be used to verify analogue circuits and mixed signal circuits.Ĭomputers now play a major role in every design field. Verilog, a hardware description language, is used to model electronic systems, and to design and verify digital circuitry at the register-transfer level of abstraction.
