I am using Primetime for sign off of my ASIC , i am doing my eco fixes in PT ,but unable to write out a changes script for cadence innovus/encouter tool
any who has done this please write how to write out a Encouter/Innovus Script for ECO Changes from Synopsys Primetime Tool ?
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.
It is sure that Industry uses PT as sign off tool and Physical Design Tool is Cadence Encounter /Innovus . So it is sure that there a method to take PT Script to innovus /encounter of cadence, I am not sure about the method, I am just asking anybody who has done this , please help
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.
