Hybrid ATE Systems Overview

• A Hybrid System – Combines components from multiple ATE platforms– Streamlines system transition and maintenance– Protects investment in existing software and hardware– Allows easy integration of advances in ATE system

development• Layered architecture is important• Multiple hybrid topologies

Issues For System Developers• Productivity

– Quickly develop tests– Reuse test programs

• Longevity– Preserve time and investment in software test programs– Minimize software changes during mid-life upgrades and

replacement• Integration with latest technologies

– Take advantage of new application development environments

6

System Management Benefits

• Improve test code reuse• Decrease development time• Simplify global design and manufacturing• Increase throughput• Allows merging of new test code with legacy test code• Accommodates software migration

9

Test Program Management and Integration• Test flow control• Sequence editor

– Create– Edit– Manage

• Support for multiple application development environments– Allows integration of new test programs with legacy test

programs• Parameter passing

– Debug– Execute– Deploy

10

Switch Integration

• Switch management• Ease of use• Reusability

– Route configurations– Alias channel names

• Execution with test programs

11

Data Management and Report Generation

• Ability to log data to multiple databases– Oracle– Microsoft Access

• UUT tracking• Various formats for report generation

– Text– HTML– ATML

12

Manufacturing Models

• Three process models provided―Sequential, batch, and parallel

• Process models control common test system components

―UUT tracking, logging, report generation, etc

• Variety of execution mode options―Test UUTs, Single Pass, Interactive, etc

13

Customization for Various Roles

• Various types of users– R&D engineer– Test engineer– Operator

• Customize abilities– Execute tests– Debug tests– Create and edit test

14

Other Considerations

• Serializing and tracking UUTs• Component and subassembly

– Tracking– Repair

• Statistical process control– Yields

15

System Benefits• Instrument Replacement

– Easily replace test programs tied to older instruments with newer test programs through test sequence editor

• Reusability– Reuse modular test code throughout system– Use test programs in other test systems

• Reduction in development time– Built in tools simplify development and management– Reuse modular test code throughout system

16

TestStand—Test Management Software• Graphical sequence editor

environment

• Automate tests written in any language

• Multithreaded sequence execution

• ASCII, HTML/Web, XML report generation

• Access, Oracle, SQL Server database connectivity
