pub fn fabricless(log: &str) -> Vec<Rect>Expand description
The tiles a probe’s fit found no flip-flop in: each region its log refuses as needing a flip-flop where there are
none (Deterministic overuse of FF resources in region (x0,y0) to (x1,y1)), a tile of the device with no logic
(hard IP, the core’s edge), which the next probe leaves out and no floorplan places a region on.
