1.2.91. MAX_BALANCING_DSP_BLOCKS

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.
