With an understanding of the basic ideas behind CMOS layout design, it is possible to create physical layout.  A good layout designer will also understand electronics pronciples such as resistance and capacitance, and understand how to reduce their effect in a CMOS circuit.

Drawing the layout of a circuit is only one half of the job of a layout designer.  The other half is verification, where the layout designer may have to re-edit their layout to correct a problem.  Even then, the circuit designer may need to alter the circuit, ranging from a minor alteration to a total re-draw.

The field of CMOS layout design, like almost any high technology field, is a dynamic work environment.  Even perfectly drawn layout is sometimes changed.  A layout designer needs to be able to adjust to these conditions, and be willing to start over again after weeks of work.
