Subject: How Do I Get DC To Buffer Every Output Port? Set_max_fanout?
John,
What's the best way to "set_max_fanout" on an output?
I would like to force design compiler to put a buffer on all output
ports, and to not use the buffered output internal to the module. The
obvious way to do this would be to do a
set_max_fanout 1 all_outputs()
but of course set_max_fanout can only be used on input ports (why???).
I can usually get what I want with the right combination of loads and
output delays on the output port, but there are cases where this
doesn't always work. Ideas?
