  19. CSI Common Software Interfaces World Wide System LSI Technology – Advanced Technology Development Department

  20. CSI: What is “Common Software Interface” ? • Abstract information model (interface) defined without implementation details • Based on Microsoft COM (Component Object Model) • Applications (CSI clients) can dynamically load software components (CSI servers) at runtime • The application remains unchanged even if new CSI servers are developed or existing servers are updated. • Concept realized in both UNIX and Windows environments World Wide System LSI Technology – Advanced Technology Development Department

  21. CSI: Implementation ISV FUJITSU EDA Tool CSI server Appl. CSI EDA Tool CSI server Appl. EDA API CSI EFFICIENCY Binary Database EDA Tool CSI server Appl. ASCII Parser CSI ASCII File EDA Tool Format Converter Appl. ASCII File ASCII File World Wide System LSI Technology – Advanced Technology Development Department

  22. CSI: De-coupling / Current Interfaces • De-coupling possible between data format & application • Data servers become totally re-usable • The only contract between server & client is the interface include file • Applications can be linked without knowing about future servers • Independent development of servers and clients possible • Current interfaces & formats supported by CSI servers • INetlist : FLDL, Verilog, VHDL • IParasitic : : SPF(RSPF, DSPF), SPEF • IPlacement : DEF • ITiming : SDF • IScanDef : DEF World Wide System LSI Technology – Advanced Technology Development Department

  23. IPSymphony 2.xMain Issues World Wide System LSI Technology – Advanced Technology Development Department

  24. IPSymphony Main Issues • Very well accepted by less experienced engineers, provides complete flow guidance with all inter-related data handling • Very fast ‘time to productivity’ for new engineering team members • Experienced engineers feel it is too restrictive • Too difficult to change methodology “on-the-fly” • Difficult to leave IPS environment, modify with external meth and return to IPS • Large effort for methodology capture / maintenance, requires detail s/w knowledge • Out-of-date features and tools (can’t catch up) • Unforeseeable delays of development and bug fixes World Wide System LSI Technology – Advanced Technology Development Department

  25. IPSymphony Main Issues • One fixed (non-configurable) design data structure results in: • Impossible to handle typical design center scenario of dealing concurrently with multiple releases of different customer hand-offs • Can’t perform multiple trials of implementation with different versions of netlists or used tools • Can’t handle version configuration management and logistics • Methodology functionality is “implanted” into CGI (capture) scripts • Prevents use of methodology functionality outside of WBE • Makes methodology capture overly complicated (merged docu, GUI, function) • Methodology documentation (flow, task description, etc.) can only be displayed if chip and block setup procedures are performed • Cannot re-use the documentation part of captured methodologies for documentation purpose only (without doing/creating things) World Wide System LSI Technology – Advanced Technology Development Department

  26. IPSymphony3 Overview World Wide System LSI Technology – Advanced Technology Development Department

  27. What is IPSymphony 3 ? • IPSymphony 3 supports • Project Management • Methodologies by using Tasks and Flows • Design Data Management • Scenario Handling • Collaboration Handling • Data coherency through dependency tracking • Common Software Interfaces for Design Data Access • Technology and environment releases are not linked World Wide System LSI Technology – Advanced Technology Development Department

  28. Architecture • Goal • Simple way of developing/capturing/delivering know-how by the methodologist • Modularity • Every component can be used stand-alone or integrated and uses interfaces for communication to other components • Layers • Complex functionality is built by adding integration layers to existing components • Flexibility • Pre-defined behavior can be easily modified locally World Wide System LSI Technology – Advanced Technology Development Department

  29. Architecture: Components • Project Database • Central storage of project configuration data • Technology and related information (like pin assignment) • Used tools and libraries • Central storage of project logistical data • Mini-milestones, status reports, check lists • Management and tracking of communication • Customer <-> Design Center • Design Center <-> Fabrication • Import/export functionality • Tool setup (e.g. SLIF) • Form generation (e.g. Design Input Form) World Wide System LSI Technology – Advanced Technology Development Department

  30. Architecture: Components • Design Data Management • Project central storage of design data files • Version control of design data files • Manipulation of data file sets • Support of scenarios, i.e. ability to follow different paths in a flow World Wide System LSI Technology – Advanced Technology Development Department

  31. Architecture: Components • Release/Collaboration Server • Delivery of libraries, tools, tasks and flows • Automatic generation and delivery of project specific library cells • Automatic logging of transfers • Automatic notification on new updates/patches • Exchange of design data • Automatic hand-off validation • Encrypted transfers • Automatic upload/download capability World Wide System LSI Technology – Advanced Technology Development Department

  32. Architecture: Components • Task and Flows • Tasks: Tool execution wrapped by standardized scripting functionality • Standardization takes care of all the “housekeeping” and makes script writing fast • All major languages (C/C++/Perl/Tcl) supported • Tcl scripting language extension allows to describe flows • Flows combine tasks to bigger units where dependencies will be tracked World Wide System LSI Technology – Advanced Technology Development Department

  33. Architecture: Components • Common Software Interface (CSI) Components • Used for • Design Data Access • Task Support • Project DB access • Decouples IPS components from implementation in various (scripting) languages World Wide System LSI Technology – Advanced Technology Development Department
