I have a request from a client to supply him with route length information by layer for a specified list of nets. I'm familiar with the spreadsheet capabilities in the Router, so I don't have any question about getting the basic route lengths, but I'm not aware of any way to break that down by layer. I'm wondering if anyone has a solution for this, such as using a Layout or Router feature in a way I haven't thought of, or perhaps a user-created Visual Basic script that can extract the route length information by layer. The client has Hyperlynx, which can do post-route analysis, but from what I can determine, only with an extra-cost option.
Thanks for any suggestions.
