1.10.171. IMPLEMENT_MLAB_IN_16_BIT_DEEP_MODE

Allows you to specify the MLAB memory blocks implementation mode. MLAB memory blocks are implemented in 32-bit deep mode or 64-bit deep mode. Turning on this option forces MLAB memory blocks to be implemented in 16-bit deep mode. This leads to significantly shorter delays and may speed up the overall design performance if the MLAB memory block is on the critical path. However, it also requires twice as many MLAB blocks to implement a given logical memory.
