In theory we could route in two layers but we've never tried it. We don't have a specialized channel router. My expectation is that we will hit some issues and have to iterate. If the PDK is closed it will be harder to do so. |

I'm sure that Fastroute and TritonRoute are capable of routing on two layers. |

My apologies if this is an obvious question. I am working with a fab trying to develop a new process that currently has 2 metal layers, and we were wondering if we could use OpenROAD/OpenLANE to build test chips. I was unable to find an answer in the documentation, but if it is there I would love to know where to look. Thank you for your help!
