1.11.12. BLOCK_RAM_AND_MLAB_EQUIVALENT_POWER_UP_CONDITIONS

Controls whether RAMs implemented in MLAB cells must have equivalent power up conditions as RAMs implemented in block RAM. Power up conditions occur when the device is powered up or globally reset. Allowing non-equivalent power up conditions will provide the fitter more flexibility in implementing RAMs using MLAB cells. If this option is set to 'Auto', the Fitter may convert RAMs to MLAB cells even if they won't have equivalent power up conditions to a block RAM implementation. The Fitter will also output a warning message notifying the user of RAMs with non-equivalent power up conditions. If this option is set to 'Don't Care', the same behavior as 'Auto' applies, but the warning message will instead be an information message. If this option is set to 'Care', the Fitter will not convert RAMs to MLAB cells unless they have equivalent power up conditions 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 'Auto' or 'Don't Care'.
