3.9. Consider the Memory Depth Setting

Use an even number to specify the memory depth or words. If you specify an odd number, the Quartus® Prime software increases the number by one during RTL generation to make it an even number.

For example, if you input "255" for the memory depth, Quartus® Prime software generates an RTL with memory depth of 256.

If you specify an odd-sized memory depth in a .mif or .hex, the Quartus® Prime software issues this warning during compilation:

Critical Warning (127005): Memory depth (256) in the design file differs from memory depth (255) in the Memory Initialization File <hex file> – setting the initial value for remaining addresses to 0.
