1.10.21. BLOCK_RAM_AND_MLAB_EQUIVALENT_PAUSED_READ_CAPABILITIES
Controls whether RAMs implemented in MLAB cells must have equivalent pause read capabilities as RAMs implemented in block RAM. Pausing a read is the ability to keep around the last read value when reading is disabled. Allowing differences in paused read capabilities will provide the fitter more flexibility in implementing RAMs using MLAB cells. If this option is set to 'Don't Care', the Fitter may convert RAMs to MLAB cells even if they won't have equivalent paused read capabilities to a block RAM implementation. The Fitter will also output an information message notifying the user of RAMs with different paused read capabilities. If this option is set to 'Care', the Fitter will not convert RAMs to MLAB cells unless they have the equivalent paused read capabilities to a block RAM implementation. To allow the fitter the most flexibility in deciding which RAMs are implemented using MLAB cells, set this option to 'Don't Care'.
