I am not sure if this can work around for analysing and the congestion .
In my understanding you mean to say about ECO -right !!
Its all depends on :
1. how many nets or instances you have modified after routing initially .
check with Eco report command
2. to analysis how big the difference just compare two report files after
even you can get map displayed .
