Critical Issue
Due to a problem in the Intel® Quartus® Prime Pro Edition Software versions 20.3, 20.4, and 21.1, you may see hardware failures when using the DSP blocks in Intel® Stratix® 10 devices. This problem is due to optimizations made during the Fitter Place stage while unpacking registers from the DSP block which results in functional mismatch between the expected data and the observed data.
