- Hi Folks!
-
- When using the long lines in the xilinx 3090 to implement a wide
- wired-AND function, must we explicitly attach a pull-up to the end of the
- long line or is this implicitly assumed when you attach a long line
- attribute to the net. The pull-up primitive that is available in most
- CAD support for the LCA's seem to refer to the IOBs pull-ups. I assume
- the pull-ups at the end of long lines are not IOB pull-ups.
-
- I am confused. Any help appreciated. Thanks.
