Why do I get incorrect results when inferring fixed-point tensor blocks in Agilex™ 5 devices?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 24.1, you might see incorrect results when targeting an Agilex™ 5 device if your designs use RTL to infer fixed-point tensor blocks. The problem occurs during synthesis when bits result_h[0], and result_l[37] of the inferred DSP block might be stuck high in hardware.  The problem does not occur in RTL simulation.

Resolution

This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 24.2
