MAX_BALANCING_DSP_BLOCKS
MAX_BALANCING_DSP_BLOCKS
Type
Allows you to specify the maximum number of DSP blocks that the DSP block
balancer will assume exist in the current device for each partition. This option
overrides the usual method of using the maximum number of DSP blocks the current
device supports. For HardCopy II devices, the number of DSP blocks represents the
number of DSP blocks used in the equivalent Stratix II device. This option is useful for
HardCopy II device migration, where the number of DSP blocks that can be
implemented in a HardCopy II device is more than the number of DSP blocks that can
be implemented in its equivalent Stratix II device. This option is also useful in
incremental compilation to set different DSP block usage limits for different
partitions.
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.
