How do I force M512 block-sized memories to be implemented in M4K blocks in the Quartus® II software?

Description

Beginning with the Quartus^® II software version 4.2, you can prevent memories from being implemented in M512 memory blocks so that memories are implemented only in M4K and MRAM memory blocks.

To prevent M512 block usage, change the setting Enable M512 to OFF under More Analysis & Synthesis Settings on the Analysis & Synthesis page of the Settings dialog box (Assignments Menu) or enter the following command in the Tcl console:

set_global_assignment -name ENABLE_M512 OFF
