• sky130ram: the macro LEFs leave met4 and all vias out of OBS (and part of met1–met3), so routes to the pins end up too close to macro metal

• asap7: FILLERxp5's gate is 0.5 nm shorter than the edge gates of many cells, so it trips GATE.S.1 between them (asap7.lydrc)

• asap7: tech LEF still uses DATABASE MICRONS 1000, so the M4/M5 EOLKEEPOUT side extension rounds onto the adjacent track and stops working (fixed in asap7sc7p5t_28 #10; ORFS #4663 was closed)
