The following table lists the block RAM and FIFO ECC attributes.

Table 1. RAMB36E2 and FIFO32E2 Attributes related to ECC
Attribute Name	Type	Values	Default	Notes
EN_ECC_WRITE	Boolean	TRUE, FALSE	FALSE	Set to TRUE to enable ECC encoder.
EN_ECC_READ	Boolean	TRUE, FALSE	FALSE	Set to TRUE to enable ECC decoder.
EN_ECC_PIPE	Boolean	TRUE, FALSE	FALSE	-
For UltraScale devices (not UltraScale+), in WRITE_FIRST or NO_CHANGE mode, if EN_ECC_READ/WRITE and EN_ECC_PIPE are set to TRUE, then both ENADDRENA and RDADDRCHANGEA cannot be set to TRUE at the same time. Consequently, the attribute combination of ENADDRENA and RDADDRCHANGEA and EN_ECC_READ and EN_ECC_PIPE cannot be set to TRUE at the same time in WRITE_FIRST or NO_CHANGE mode.
