Self test device and self test method for reconfigurable device mounted board
First Claim
1. A self test device that performs a self test of a board on which a reconfigurable device is mounted, the self test performed during an operation of the board, the self test device comprising:
- an element calculating unit configured to calculate operational elements to be used in a device of the board for the operation, and non-operational elements, based on operation parameters for a time of the operation of the board;
an element assigning unit configured to assign an element to a self-test target from among the non-operational elements; and
a testing unit configured to make a test signal transmit through a test path that passes through the self-test target to perform a test on the self-test target.

Abstract
A self test device includes an operational element determining unit that calculates, based on operation parameters for the time of operation of a board on which a reconfigurable device is mounted, operational elements used in the devices of the board for the operation, and non-operational elements; an element assignment determining unit that assigns a self-test target from among the non-operational elements; and a testing unit that makes a test signal transmit through a test path that passes through the test target.

11. A method of performing a self test of a board on which a reconfigurable device is mounted, the self test performed during an operation of the board, the method comprising:
-
calculating operational elements to be used in a device of the board for the operation, and non-operational elements, based on operation parameters for a time of the operation of the board; assigning an element to a self-test target from among the non-operational elements; and performing a test by transmitting a test signal through a test path that passes through the self-test target to perform a test on the self-test target. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
