The designers choose a method of circuit construction as well as the parts and components to be used.
Then the designers research the specifications of components and interaction between components (especially timing and loading ), calculate the component values to meet the operating specifications.
During the design of the circuit, some portions of circuit may have been tested by simulation or breadboarding.
PCB layout are derived from the circuit diagram, the components and connections are placed and routed by the designer to get the best result. When the PCB layout is complete, the final CAD file is sent to a PCB manufacturer.
