From cmrf$7$sf $(0\mathrm{.}18$um CMOS of IBM$)$ library use nfet$\_$rf $($nmos$)$ and pfet$\_$rf $($pmos$)$ devices, draw the circuit schematic of "inverter" using nfet$\_$rf and pfet$\_$rf device symbols and connecting corresponding terminal pins, draw layout using default nfet$\_$rf and pfet$\_$rf device$-$cells used in the circuit schematic and then run $"$DRC$"$ and $"$LVS$$ for verification. Submit report with: $($a$)$ circuit schematic window, $($b$)$ layout window. $($c$)$ DRC results window and $($d$)$ LVS results window.
