Using the openlane docker environment, what is considered a successful flow (e.g., ./flow.tcl -design xtea)? Using the xtea design as an example, I see it has negative slack (timing errors), but tritonRoute.drc is empty which I'm assuming means no drc errors. What other possible errors should I look for?

I think it's more appropriate to move this question to #openlane channel

Ok, I posted in there. Thanks.
