Routing congestion calculation

[coherent17]

Hi Rapidwright expert and maintainer, I have a quick question about how to extract the routing congestion in rapidwright with the design after Vivado place and route stage?

Currently, I have the dcp & edif and I can use rapidwright to iterate the Design database.

Is there any suggestion or recommendations to calculate the routing congestion value or interconnect density on rapidwright?

Thanks and regards!

@coherent17 there are probably many ways to calculate routing congestion or to identify how routing is being utilized in a design. Here is a simple example to generate a routing heat map by tabulating routing resources used in INT (interconnect) tiles of a placed and routed design: #1145. Try it out and take a look at the code to see if it can spark any ideas for what you are imagining.

Hi @clavin-xlnx ,

Thanks for the branch to demo!
The pull request actually gives me a great start on routing heat map!

Thanks for your sharing!
