@User sky130 pdk defines a .OPTION SCALE=1e-6, so all dimensions are automatically scaled down by 1e6, a W=650000u (=0.65) translates to W=0.65u automatically, a L=150000u (=0.15) scales to 0.15u. Why a 150000u instead of just 0.15 is used i don't know, this is probably due to some automatic file processing.
