Circuit board design support program, design support method, and design support apparatus

The embodiment is a non-transitory computer readable storage medium storing a design support program which causes a computer to generate design data for a circuit board in which elements are placed. The program causes the computer to perform: storing, in response to an operation input, operation information in an operation storage section; storing a function of a program executed based on the operation input in a function history storage section; upon detection of an operation of a command causing the computer to execute a predetermined function for generating the design data, acquiring a selected element and storing the selected element in an element information storage section; and detecting an abnormal end of the predetermined function to output the function of the program in the function history storage section, the operation information in the operation information storage section, and the element in the element information storage section to a log file.
