Hi John,
I went through Trisha's "How to" http://deepchip.com/items/0416-05.html
on ESNUG recently.
My question is not directly related to PrimeTime environment.
I am unable to understand the -apollo_eco switch functionality. My guess
is that this will generate some kind of Scheme file for Astro/Apollo. I
would like to know what kind of information is passed to Apollo through
this file.
If I am using Astro Xtalk, I can use its repair feature to work on the
information provided by CeltIC.
But in Apollo how can we repair the nets without Astro Xtalk repair
capability?
Let me know if my understanding is not correct.

Hi, John,
The -apollo_eco switch enables the generation of an ECO file for
Apollo/Astro. It generates scheme commands that tell Apollo/Astro what
to do, for instance to perform a buffer insertion on a net.
I am not familiar with the licensing of Apollo/Astro, so I do not know
if there is a special license/feature that you need to enable the ECO
fixing capabilities.
