There was a problem hiding this comment.
I think this can be simplified to assert ref in self.refs, ref?

This is an initial version of BELs chains support. This is related to SymbiFlow/nextpnr#262
The main target for now is to get carry chains support for xilinx architectures, but the solution should be applicable for any architecture in the end. The PR includes what type of data we should pass to nextpnr in order to get the constraining step done of the BELs chains.
