MAX_RAM_BLOCKS_M512
MAX_RAM_BLOCKS_M512
Type
Allows you to specify the maximum number of M512 memory blocks that the
Compiler may use for a device. This option overrides the usual method of using the
maximum number of M512 memory blocks the current device supports, when the
value is non-negative and is less than the maximum number of M512 memory blocks
available on the current device.
This option is also useful in incremental compilation to set different M512 memory
block usage limits for different partitions.
This option can be used 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 is useful for device migration.
