synchronus reset on bufg? (xilinx)

  • Follow


Hey all,
I have a synchronus reset signal that has a very large fanout.
Is it advisable to put this signal on a bufg?

Thanks

Howdy Matt,

Unfortunately, the global clock buffers are only usable for clocks on 
Xilinx devices.  Since it is synchronous, you might try letting the 
tools chew on it (if you haven't already) with local routing and see 
what timing results.  If that is too painful, consider switching to the 
GSR (there are safe and easy ways to use it).

Good luck,

    Marc
