X_INTERFACE_INFO

Can someone tell me where the list of possible values for the X_INTERFACE_INFO attribute can be found?  I need to set a number of outputs of my block to type "OTHER" or something like that to clean up the block and to eliminate some critical warnings.

Re: X_INTERFACE_INFO

I found this to be interesting in ug994 v2019.1:  chapter 13, search for "List of Supported X_ Attributes".  One of them is X_INTERFACE_INFO.  Not sure about the second part of your statement.

Re: X_INTERFACE_INFO

@dlevasseur,  A three month old post answered by a Newbie.  Thanks.  It looks like the proper way for me to do what I want would be to use the X_INTERFACE_IGNORE attribute.  I ended up setting the X_INTERFACE_INFO attribute of my signals to "undef", which is not a supported attribute, but Vivado doesn't try to assign a supported signal type, it just throws a warning.
