  1. SUMMER STUDENT Programme @cern Maria Iliadi BE - BI - SW

  2. BEAMS + BE / BI Group BEAMS: Hosts the Groups responsible for the beam generation, acceleration, diagnostics, controls and performance optimization for the whole CERN accelerator complex Beam Instrumentation Group: is responsible the diagnostic systems that allow observation of the particle beams and the measurement of related parameters for all CERN accelerators and transfer lines. BE / BI Group

  3. BE - BI Software Section Responsible for the software of all the diagnostic systems that give information to the instruments produced by the BI Group - Develop Real Time Front End Software for the instruments including the remote control communication interface. - Develop Expert Graphical User Interfaces [GUI] for the instruments - Develop tools to allow the HW specialists to build their own test programs.

  4. About FESA... Front-End Software Architecture framework A complete environment to design, develop, test and deploy real-time control software for front-end computers

  5. Fesa Graph A simple FESA Class Control Flow graph generator B.Bielawski - BE-CO-FE Python 2.7+ & Graphviz

  6. Fesa Graph A simple FESA Class Control Flow graph generator B.Bielawski - BE-CO-FE Python 2.7+ & Graphviz .dot

  7. Fesa Graph • Identifying errors and enhancements • A nice picture of the implementation • Distinguish differences between the model and the respective implementation • Macro processors for generating different diagrams

  8. Clear, easy to read • Less nodes • Keep the important attributes only • Understand with a quick look

  9. My goals • Retain only useful information • Remove trivial attributes • Improve the process of generating flowcharts TARGETS

  10. Basic Steps 1 Understand the basic consept behind FESA 2 Study DOT language and Graphviz documentation 3 Understand the existing code and test it Improvements, implementation & feedback 4

  11. Less nodesets – easy to read • A clear flowchart • More logical • No trivial attributes • Works on every class Achievements

  12. Next Steps • Check for other improvements • GUI (including the LEGEND)
