Verilog always @ posedge with examples – 2021 Verilog by VLSI Universe - June 13, 2021July 21, 20210 Verilog always block (blocking and non-blocking assignments) is explained in detail with examples. Also generation of MUX and Decoders Verilog. In any digital interview, Verilog questions will be asked. Simple questions to confuse and tricky questions will be asked by an interviewer. He will be interested in knowing whether you are very clear with basic concepts or not. Verilog is a hardware description language that makes it necessary to be learned by a digital design aspirant. Questions on blocking and non-blocking assignments, Verilog tasks vs Verilog functions, and Verilog modeling questions based on synthesis are the key concept-oriented ones that are preferred to ask by the interview panel. Well, let us cover some of the important concepts in Verilog HDL. Verilog always block and
Verilog code for sine cos and arctan using CORDIC Algorithm Verilog by VLSI Universe - June 3, 2021July 21, 20210 Hardware implementation of trigonometric functions such as sine, cosine and tangent functions using Verilog HDL. Here we make use of CORDIC algorithm to implement these functions in Verilog. It is important to to write a synthesizable code in Verilog to implement on hardware such as FPGA's. The computation of the functions helps to analyze sine wave generation and phase and magnitude calculation of several signals. 1. Basics of CORDIC Algorithm 1.1 Need for CORDIC Algorithm There are several approaches such as the Lookup table method and Polynomial series (for example, Taylor series) to implement these sine, cosine and tangent trigonometric functions. They have complications such as cost of the implementation and the hardware complexity of the design. In case Lookup table method it is fast
