@jeffdi @Matt Venn hello I met such problem in detail routing, please give me some advice to check
v
file github issue here: https://github.com/The-OpenROAD-Project/OpenLane/issues and reproducible test case
m
yeah, definitely need more info - pls do as @Vijayan Krishnan suggests
a
seems you have a pin named vccd1. Do you have power pins declared?
Post verilog code and config.tcl
b
one issue for me was macro could be too small
another issue is wrong connections such as connection an output port signal of a module to an input port of the top module
check synth warnings

The detailed router should not be working on vccd1 as that should be marked as a power net. You have something wrong in your earlier setup
