In the Gowin documentation for BSRAM 2019, the byte_enable port and its operation and use in generating IP with pictures were described in detail, two years later in the same document the byte_enable port was listed as supported only for the NS-2 family, and finally in the 2023 edition, all references to both the NS-2 family and the byte_enable port were removed.
I don’t know, maybe it turned out that they forgot the transistor there and it works unstable or something else, but at the moment I’m thinking of using only fixed values when inferring. You can use anything manually - after all, these are just lsb addresses.
