Honored ContributorHello,
I have been using the tristate buffer (from primitives/buffer folder) to control a byte wide bus. I have noticed a number of warnings while compiling and was wondering if this feature was designed for a single line, or if it can handle larger bus lines? If not, what is the alternative for this case? Thanks. Andre
Honored ContributorI guess, you are talking of bidirectional buffer in schematic entry. It can also be used with busses, as many other elements too. I wouldn't expect that the warnings are related to connecing a bus to the buffer.
Honored ContributorSince there is no physical tristate bus inside an FPGA the Quartus software has to generate a multiplexer logic that replaces the logical tristate bus. Maybe the warnings are caused by this multiplexer logic?
Honored ContributorI have changed a few things and the warnings have disappeared. I guess I misinterpreted what was meant by the warnings. Thanks for your input.
