Is there a way to use CTS with differential (diffpair) clocks?

TomLM

Hi,

 I am researching an implementation idea to use Clock Tree Synthesis (CTS) to route a clock tree that consists of a differential clock.  The desired results would be a clock tree that is routed as a diff pair, with differential / matched buffering throughout.

Thanks.

  • You are going to need the Cadence mixed signal "Virtuoso Layout Suite GXL" option to do clean diff pair clock routing.
    There is a chapter in the encounter user guide worth reading "Using the Encounter Mixed Signal Router"
    I successfully used it for a "one off"  bicmos chip over 15 years ago, it was fairly easy to learn.
