As soon as we get a chance to characterize and push our current update (hopefully by end of week), we'll also have: • Multiple track versions. Original was 18T. 15T, 12T, and 9T version have been made since then, and are just awaiting characterization. • Better balanced clkinverters. You noticed correctly that in our original push, CLKINVs and INVs had the same dimensions. That's because in our original push, we based the CLKINV dimensions on non-PEX characterization, and indeed our INVs were perfectly balanced. Adding in PEX upsets that balance. The SkW cells don't have PEX, so all things aside inherently cannot be as well-balanced.
