third party global routing

yazdan

Hi,

 I want to do the global routing of my design with another tool. Is it possible to save the design after the placement? and then do my global routing in another tool and after that provide the data required for cadence to do detailed routing.

 Thanks

  •  Hi Yazdan,

     I don't know what kind of output your 3rd-party tool can provide to describe the global routing (you mention DEF, but what does it really look like?), but global routing (at least in the Cadence tool sense) isn't real routing, like a detail route. I don't think there is a way to represent it in DEF.

    Can I ask why you don't want to have EDi do the global and detail route together? Can you post a bit of what the DEF global routing looks like from your other tool?

     I don't think this flow is possible, but it would help to know more about what you're trying to achieve.
