Dds Compiler 6.0 Example Jun 2026

The 6.0 version (often associated with recent Vivado releases) introduces improved AXI4-Stream interfaces and better support for High-Level Synthesis (HLS) integration compared to older legacy versions. It offers a balance between Block RAM (BRAM) usage and DSP slice utilization, allowing engineers to choose the implementation that best fits their resource budget.

reg [31:0] tuning_word; always @(posedge clk) begin if (change_freq) begin if (tuning_word == 32'h028F5C29) tuning_word <= 32'h0147AE14; // 500 kHz else tuning_word <= 32'h028F5C29; end end

This article provides a deep dive into the DDS Compiler 6.0. We will explore the architecture, configure a practical step-by-step, and walk through the Verilog implementation required to drive it. Dds Compiler 6.0 Example

Set to 16 bits (standard for many audio DACs or high-speed ADCs). Implementation Tab:

Where:

Generate a 1 MHz sine wave with 100 MHz system clock.

Before diving into the example, it is essential to understand what the IP core actually does. The DDS Compiler 6.0 implements a sine/cosine generator based on the principle of phase accumulation. We will explore the architecture, configure a practical

The is a high-performance intellectual property (IP) core designed to generate sinusoidal waveforms with high precision and spectral purity . This core is a staple in Digital Signal Processing (DSP) applications, such as digital up/down converters, modulators (PSK, FSK, MSK), and frequency synthesizers.

Our example used phase increment. For real SDR or FSK modulation, you need dynamic frequency changes. Here's how to modify: Before diving into the example, it is essential

: By outputting each frequency for 1 microsecond, you create a visible sweep across 25 MHz in roughly 26 microseconds. Accessing the Official Example Design
