ARCHIVING VERSUS VERSION CONTROL Archiving Version Control Track how data changes over time. Backup the data, possibly on multiple locations (redundancy). Control accessibility (user access control). Timestamped (time of archivation/file creation) May reduce data size (compression) Track who changes the data (commiter). Define snapshots (commits). Acts as a time machine for data. Allow diverging timelines (branching). Allow converging timelines and provide ways to integrate changes from different timelines into one (merging). Can accomodate all data types.

DATA ACCESSIBILITY Proprietary Data: Who can access? Wafer design files How to gain access? Technology related measurements How to transfer? Software & Firmware development Who can transfer? Collaborative Data: ASIC design/tests System specifications In between: Software releases PR plots/measurements Documentation M A X P L A N C K S O C I E T Y S E M I C O N D U C T O R L A B O R AT O R Y O v e r v i e w : D a t a A r c h i v i n g & Ve r s i o n C o n t r o l – M a r t i n H e n s e l 1 5 . 1 2 . 2 0 2 2 5

VERSION CONTROL SYSTEMS Human readable files: Industry standard Binary files: It‘s complicated We employ the industry standard: git Every binary file type is different. Other tools are available as well, e.g. SVN Data comparison almost impossible. The differences are mostly in administration style and where the data is stored. Most version control tools are proprietary and handle only a small subset of all possible binary data types. On top: Usablility User interface to work with the basic system A way for collaborators to interact with the data and each other Process automation (CI/CD) Documentation M A X P L A N C K S O C I E T Y S E M I C O N D U C T O R L A B O R AT O R Y E.g. Cadence Design Entry HDL: Version control of PCB schematics (HDL) via MS SharePoint server. - But no support for PCB layouts (boad files), although created with the same software suite.

PRODUCT LIFE CYCLE MANAGEMENT Many tools provide much more functionality: This sounds like a lot, but . Project planning and time tracking Work force deployment and load optimization it may be the only solution that encompasses a good chunck of a development task, e.g. PCB design from schematic, via simulation to layout. Manufacturing process tracking EDM integration (e.g. SAP orders from BOM) Management sugar: colorful plots about nothing it can be used as a common interface between several individual version control systems and bridge the gaps left by them. Issue tracking After-production: marketing, rollout Knowledge bases and documentation that may be true, it can be a total waste of time and manpower to manage such a system. Efficiency scoring (e.g. yield analysis) And many more M A X P L A N C K S O C I E T Y S E M I C O N D U C T O R L A B O R AT O R Y O v e r v i e w : D a t a A r c h i v i n g & Ve r s i o n C o n t r o l – M a r t i n H e n s e l 1 5 . 1 2 . 2 0 2 2 7

DISCLAIMER The following slides can only show a small part of the available products that can be used to perform the described tasks. The presented lists cannot – and are not intended to – be complete representations of the market. I have worked with some of the tools in the past. That introduces an inherent selection bias for some tools over others, based on previous experiences and ignorance about possibly superior alternatives and recent developments.
