reset tree generation in Encounter

archive

 Dear All,

 I'd like to ask if there is a methodology for routing async reset signals to flip flops. Should I perform another CTS-like step to create a buffer tree specifically for the reset signal or just leave it up to the NanoRoute?

 

Thanks,

Alex

  •  I don't normally use CTS to buffer resets. I have a max fanout setting in my constraints and I just let the optimization command use that constraint to buffer the reset net. But you can use CTS to buffer the reset if you want. This will allow you to control timing better on the reset net if it is needed.
