A driving design method for ATE (automatic test equipment) instrument, is characterized in that, comprise the steps:
The first, set up principle of instrument block diagram, the Interface Terminal that editor's instrument is external, for each terminal edit properties;
The second, in theory diagram, set up instrumental function module, be divided into signaling module, port module two type, the type that often kind of module comprises is unique;
3rd, for each signaling module sets up signal, the attribute information of concrete distributing signal;
4th, for each port module sets up port, the concrete attribute information distributing port, and be connected with the external interface terminal of instrument;
5th, according to instrumental function, the signal of signaling module is connected with the port of port module, for each external interface terminal of instrument sets up signal attribute;
6th, the function for the opening of every platform instrument, initialization, self-inspection, reset, closedown and instrument self is programmed;
7th, configure instrument univers parameter.
The terminal attribute information of described step one comprises terminal names, terminal types is selected, terminal numbering.Wherein, terminal types comprises one-wire terminal, dual wire terminals, two-wire coaxial terminal, three line coaxial terminals, multi-thread terminal.
The signal attribute information of described step 3 comprises signal name, character types, signal type, parameter information; Wherein, character types comprises excitation and measures; Signal type comprises voltage, electric current, power; Parameter information comprises numerical range, unit, error range.
The port attribute information of described step 4 comprises that port name claims, port type, port are connected with the external interface terminal of instrument; Wherein, port type comprises single line, two-wire difference, two-wire is coaxial, three lines are coaxial, two-phase, three-wire, four lines.
