Mar 13, 2018 · In this tutorial, I am going to demonstrate different methods to generate a sinus wave in an FPGA with Verilog and VHDL. I am going to program and test the functionality with Vivado 2017.4. This is going to be divided into 3 parts: Fixed frequency, variable frequency and a PWM sinusoidal signal.

Oct 31, 2024 · This code efficiently generates and stores sine wave coefficients as integers, reducing memory usage while maintaining precision. It produces values with 10 bits of resolution for amplitude and 1 bit for the sign, making them ideal …

Nov 13, 2024 · The waveform does not look like a sine wave. This is because you must change the radix setting from Hex to Signed Decimal, as described in the following subsection. Right-click U_SINEGEN/sine[19:0] signals, and select Radix > Signed Decimal .

Nov 7, 2024 · Learn how to design and implement a Numerically Controlled Oscillator (NCO) in Vivado using a block design approach! This tutorial walks you through creating a variable-frequency sine wave generator using FPGA technology. Key topics covered: You can find the complete video here:

Oct 30, 2024 · This tutorial demonstrates how to effectively utilize the Xilinx Block Memory Generator in FPGA designs to create dual-frequency sine wave generators. The video walks through creating a design...

Using Vivado IP generator for Sine Wave To make it short and sweet, and I need to emulate an ADC that transmits at 5.6 GB/s using a Virtex-7 board. I do not necessarily need the analog waveform because the digital one is all I care about.

Dec 11, 2024 · Observe the sine signal output in the waveform. The Wave window can be unlocked from Main window layout to view it as standalone. Click the Float button in the title bar of the Waveform Configuration window. Click the Zoom Fit button to display the whole time spectrum in the Waveform Configuration window.

Nov 13, 2024 · After doing some setup work, you use Vivado logic analyzer to verify that the sine wave generator is working correctly. Your two primary objectives are to verify that: All sine wave selections are correct. The selection logic works correctly.

Three possibilities to look at. You may be displaying a signed number as unsigned, you may be displaying an insigned number as signed, or one of yur busses needs an extra bit and your signal is overflowing, thus wrapping around.

Mar 24, 2015 · To see the sin/cos wave with Vivado, right-click on the sin/cos signal and select 'waveform style' and then 'Analog'. (Be sure that you run the simulation for enough time.) Share
