    Re: Timing Sign off from Primetime

    First, let me say I am not sure this functionality is possible, encounter is meant to work with its own STA engine. I am sure you can create the scripts yourself, but that would be a lot of work.

    Second, why are you using the ECO flow for? To fix timing? That is almost always a bad idea.

    Re: Timing Sign off from Primetime

    Check this link, it might be helpful. The guy is essentially doing ECO by hand http://tech.tdzire.com/timing-eco-flow-with-examples/

    Again, I think you should understand the goal of this exercise before going down the rabbit hole. PT works with ICC. Innovus works with Tempus. In the newer technology nodes you care a lot about convergence, leaving Innovus to do STA in PT is asking for trouble.
