ABSTRACT:
An electronic checklist program is provided for commercially available printed circuit board layout design programs. The checklist program creates a file which is appended to a design file created by the layout program. The checklist program has step menus indicating steps for each interval to be completed in the layout design. When steps in an interval are completed, the time is logged for each and when an interval is done, the cumulative time is logged. The program tracks the last step completed such that on start-up with a previously created design, the program skips to the screen including the last completed step. Provision is also made to churn completed intervals and log churn time.
