How to Generate Vivado-like Timing Report and Extract Routing Mux Delays in RapidWright?

[gigaAlter]

Hi, I have two questions regarding RapidWright and would appreciate your guidance:

1. Is there a way to load a routed DCP in RapidWright and generate a timing report similar to what Vivado provides?
2. When printing the critical path using RapidWright, is it possible to include more fine-grained details such as the routing multiplexer delays between slices?

Thanks in advance!

RapidWright does not have access to the production timing delays held by Vivado. It does, however, have an lightweight and approximate timing model that allows timing-driven decisions to be made.

1. https://www.rapidwright.io/docs/ReportTimingExample.html describes how this model is used to generate an approximate timing report
2. Approximate delays of routing resources are described in our timing model paper: https://www.rapidwright.io/docs/_downloads/6610b931d8a2e053e69a499d3923077f/FPT19-TimingModel.pdf

Thanks a lot! will go through it carefully.
