Solving: ( B_\theta \approx \log_2(10^8) \approx 26.6 ). So a 27-bit accumulator yields <1 Hz resolution. Let's use for safety and better SFDR.
: A simple counter or accumulator is used to recursively add a fixed "phase increment" value to itself. This shifting input value is then fed into the DDS Compiler's phase input, which changes the frequency of the generated sine wave at every step. Dds Compiler 6.0 Example
To see the waveform physically, you need a DAC. Connect the 12-bit sine_out to a DAC (e.g., AD9708 or a simple R-2R ladder). Use an oscilloscope: Solving: ( B_\theta \approx \log_2(10^8) \approx 26
Below is a detailed guide and example for implementing the DDS Compiler 6.0 in a Xilinx Vivado environment. 1. Understanding the Core Architecture : A simple counter or accumulator is used
Choose "Block RAM" for large tables or "Distributed ROM" for small, high-speed applications.
