1.2.94. MAX_NUMBER_OF_REGISTERS_FROM_UNINFERRED_RAMS

Allows you to specify the maximum number of registers that Analysis & Synthesis can use for conversion of uninferred RAMs. You can use this option as a project-wide option or on a specific partition by setting the assignment on the instance name of the partition root. The assignment on a partition overrides the global assignment (if any) for that particular partition. This option prevents synthesis from causing long compilations and running out of memory when many registers are used for uninferred RAMs. Instead of continuing the compilation, the Quartus Prime software issues an error and exits.

Type

Integer

Device Support
