MAX_RAM_BLOCKS_MRAM
MAX_RAM_BLOCKS_MRAM
Type
Allows you to specify the maximum number of M-RAM or M144K memory blocks
that the Compiler may use for a device. This option overrides the usual method of
using the maximum number of M-RAM or M144K memory blocks the selected device
supports, when the value is non-negative and is less than the maximum number of M-
RAM or M144K memory blocks available on the current device.
This option is also useful in incremental compilation to set different M-RAM or
M144K 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.
