Highlight routing in Chip Planner

Hello,

The reason you cannot highlight a route in chip planner from RTL viewer is because the RTL viewer is the synthesised RTL code you have written (Analysis & Synthesis stage). From there Quartus will perform place & route and also register retiming during the Fitter stage so the routes in the chip planner are entirely different from what you see in the RTL viewer. This is why you don't have the option to highlight route in Chip Planner from RTL viewer.

My suggestion is to cross probe from Timing Analyzer as you can locate path in Chip Planner from here. What you can do is report timing of the particular node you want to highlight in Chip Planner.

You can also do the report_timing on Timing Analyzer GUI. On Timing Analyzer, go to Reports>Timing Slack>Report Timing. In your targets, you can go to From and click on the 3 dots to open Node Finder and search for u_leaf_4.

From the report, you can right click on the path and locate in Chip Planner.
