6.1 System Generator for DSP - Why do I get an error when trying to generate the DDS to use phase dithering if the phase angle is greater than the phase accumulator width?

Description

Keywords: SysGen, MATLAB, Simulink, DDS, phase dithering, phase angle, phase accumulator, 2.2, 2.3, 3.1, 6.1

Why do I get an error when trying to generate the DDS to use phase dithering if the phase angle is greater than the phase accumulator width?

COREGen may report the following error:

"ERROR: Customization parameter rule checks failed.
Terminating core elaboration:
Phase dithering only available when Phase Accumulator Width is greater than Phase Angle Width."

Solution

This is a known problem that was fixed in the System Generator for DSP 6.2 release.

You can use the phase dithering only if the phase angle is less than the phase accumulator width.
