Equivalent RAM and MLAB Power Up logic option

A logic option that controls whether RAM blocks implemented in MLABs must have power-up conditions equivalent to block RAM implementation. Power-up conditions occur when the device is powered up or globally reset. Allowing non-equivalent power-up conditions provides the Fitter more flexibility in implementing RAM blocks using MLABs. If this option is set to Auto or Don't Care, the Fitter may convert RAM blocks to MLABs, even if they do not have equivalent power-up conditions to a block RAM implementation. If this option is set to Auto, the Fitter generates a warning message identifying RAM blocks with non-equivalent power-up conditions; if this option is set to Don't Care, the Fitter generates an information message identifying RAM blocks with non-equivalent power-up conditions. If this option is set to Care, the Fitter does not convert RAM blocks to MLABs unless they have equivalent power-up conditions to a block RAM implementation. To allow the Fitter the most flexibility in deciding which RAM blocks are implemented using MLAB cells, set this option to Auto or Don't Care.
