• Thanks!
• Right now, our CLKINV is 3/1 p/n width ratio, as according to the spice models this makes it balanced.
• There will be different drive versions of all the cells. Right now, all or nearly all cells have X1 and XL (low-drive). Most cells also have X2 and X4, and a few of the simple ones have X3, X4, X6, X8, X10, X12, X16. It's just a matter of man-hours to create higher drive-strength versions of other cells as well.
