Abstract
A multi-strobe apparatus for generating multi-strobe having a plurality of strobes is provided, wherein the multi-strobe apparatus includes a clock generating unit which is able to generate a signal for adjustment at a timing at which each of the plurality of strobes should be generated; a strobe generating circuit for generating the plurality of strobes; and an adjusting module for adjusting a timing of the strobe generating circuit's generating each of the strobes on the basis of the signal for adjustment.
Claims13
A multi-strobe apparatus for generating multi-strobe having a plurality of strobes comprising:
- a clock generating unit which is able to generate a signal for adjustment at a timing at which each of the plurality of strobes should be generated;
- a strobe generating circuit for generating the plurality of strobes;
- and
- an adjusting module for adjusting a timing of said strobe generating circuit's generating each of the strobes on the basis of the signal for adjustment.
A testing apparatus for testing an electronic device comprising:
- a pattern generating unit for generating a test pattern for testing the electronic device;
- a pattern formatter for formatting the test pattern and providing the electronic device with it;
- and
- a determining unit for determining pass/fail of the electronic device on the basis of an output signal output by the electronic device according to the test pattern,
- wherein said determining unit comprises a multi-strobe apparatus for generating multi-strobe having a plurality of strobes for detecting a value of the output signal, and
- said multi-strobe apparatus comprises
- a clock generating unit which is able to generate a signal for adjustment at a timing at which each of the plurality of strobes should be generated;
- a strobe generating circuit for generating the plurality of strobes;
- and
- an adjusting module for adjusting a timing of said strobe generating circuit's generating each of the strobes on the basis of the signal for adjustment.
A testing method for adjusting a timing of generating each of a plurality of strobes included in multi-strobe comprising:
- a signal for adjustment generating step of generating a signal for adjustment at a timing at which each of a plurality of strobes should be generated;
- a strobe generating step of generating the plurality of strobes;
- and
- an adjusting step of adjusting a timing of generating each of the strobes in said strobe generating step on the basis of the signal for adjustment.
