This presentation gives an introduction to the technical file and version control management problems typically experienced by engineers in the Electronic Design Automation (EDA) industry. We start off by discussing the complexities and challenges of managing complex designs, using FPGA design as our example. Next we look at the IEEE IP-XACT standard which was created to address these issues. Lastly, we discuss possible solutions and show how Scineric Workspace, which is based on this IEEE standard, can be used to solve most of these problems.

- 11. It’s the year 2013 20nm devices in production yet, most EDA tools doesn’t even support version control however, things are changing
- 12. IP-XACT: We Are Not Alone • IP-XACT Standard published by IEEE in 2009 • Huge in scope, subset of standard addresses the challenges described here • Lack of user friendly tools, industry adoption slow http://scineric.csir.co.za © CSIR 2013
- 13. IP-XACT: How Does It Work • On design level, designs tagged using VLNV tags • You add one IP-XACT based xml file to your design’s directory which is used to describe and manage your design http://scineric.csir.co.za © CSIR 2013
- 14. IP-XACT: How Does It Work • This IP-XACT component file stores the information needed to solve the many of the challenges discussed • You don’t need to know that it exists. The goal is that things just work from a user perspective http://scineric.csir.co.za © CSIR 2013
- 15. Where Does Scineric Fit In?
- 16. Scineric: An IP-XACT based IDE • Scineric is an IP-XACT driven IDE • It extends the standard to help address the challenges mentioned • Its modern, fresh and doesn’t lock you in http://scineric.csir.co.za © CSIR 2013
