I've hit an error with openlane straight out of the box, following the install instructions on github and then running the 'spm' design. The one thing that is different is that I selected the '..._hs' cells so I'm guessing it's something to do with that. Does anyone has any pointers on how to get past this?

Running antenna checks.

Hi, @yrrapt, I will check this issue soon enough. However, I'd advise you experiment with the other libraries as their configurations were more tested and improved, especially the hd library. Then, the ls and hdll. But, the ms and hs libraries still have a couple of issues and need more optimizations.
