Routing Heat Map Example

[clavin-xlnx]

A simple example application that reads in a DCP and outputs a CSV of the routing used in each INT tile of the design. This can be imported into Excel and using the conditional coloring option by selecting all of the non-empty cells:

This can then generate a heat map of routing congestion:

To run this example from scratch:

git clone -b routing_heat_map --recursive https://github.com/Xilinx/RapidWright.git
cd RapidWright
./gradlew compileJava
bin/rapidwright RoutingHeatMap test/RapidWrightDCP/picoblaze_2022.2.dcp picoblaze_2022.2.csv

Then you can open the csv in Excel or a similar tool.
