Abstract
A multi-strobe generation apparatus for generating a multi-strobe has a plurality of strobes. The multi-strobe generation apparatus includes a shift clock generating section which outputs a shift clock generated by dividing a reference clock at a timing at which each strobe is generated, a strobe generating section for generating the multi-strobe corresponding to each leading or trailing edge of the reference clock, and an adjustment section for adjusting timing at which the strobe generating section generates each strobe based on the shift clock.
Claims20
A multi-strobe generation apparatus for generating a multi-strobe having a plurality of strobes, comprising:
- a shift clock generating section which outputs a shift clock generated by dividing a reference clock at a timing at which each strobe is generated;
- a strobe generating section for generating said multi-strobe corresponding to each leading or trailing edge of said reference clock;
- and
- an adjustment section for adjusting timing at which said strobe generating section generates said each strobe based on said shift clock.
A test apparatus for testing electronic devices, comprising:
- a pattern generator for generating a test pattern for testing said electronic device;
- a pattern formatter for formatting said test pattern to supply to said electronic device;
- and
- a judging device for judging pass/fail of said electronic device based on an output signal output by said electronic device corresponding to said test pattern,
- wherein said judging device comprises a multi-strobe generation apparatus for generating a multi-strobe having a plurality of strobes for detecting a value of said output signal, and said multi-strobe generation apparatus comprises:
- a shift clock generating section which outputs a shift clock generated by dividing a reference clock at a timing at which each strobe is generated;
- a strobe generating section for generating said multi-strobe corresponding to each leading or trailing edge of said reference clock;
- and
- an adjustment section for adjusting timing at which said strobe generating section generates each strobe based on said shift clock.
An adjustment method for adjusting timing for generating each strobe of a multi-strobe having the plurality of strobes, comprising:
- a shift clock generating step for generating a shift clock generated by dividing a reference clock at a timing at which each strobe is generated;
- a strobe generating step for generating said multi-strobe corresponding to each leading or trailing edge of said reference clock;
- and
- an adjustment step for adjusting timing at which said strobe generating section generates each strobe based on said shift clock.
