ID:15926 RAM Primitive "<name>" uses ECC feature but it can't be implemented in 2Kx64 simple dual-port mode.

CAUSE: The specified RAM atom is using ECC and it can't be implemented in 2Kx64 simple dual-port mode. When ECC feature is used, the RAM must have the depth no more than 2K and data width no more than 64 and in simple dual-port mode. In addition, it can't use mixed-width.

ACTION: Check your design and make sure the RAM atom can be configured in 2Kx64 simple dual-port mode or disable the ECC feature.
