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'.
