Integration experiences
Integration Experiences

  • Efforts

    • 5 man months, all C++ code

    • dbTraverse: 2500 lines

    • DB interface: 8700 lines

    • OpenAccess Specific Code: 12000 lines

    • Total 23,200 lines C++ Codes by 5 man months efforts

    • Might need another 6 man months effort for integration with new OpenAccess release and quality assurance   

  • Highlight

    • Excellent documentation

  • Lowlight

    • Need more detailed and complete examples on database traverse (i.e.oaRegionQuery)

      • We got many problems from oaRegionQuery

      • Hope we can learn from database viewer to be available in Dec. 2003 release?

    • May have to propose ways to solve oaRouteSeg and oaVia within oaRoute object

      • oaRouteSeg and oaVia are not db objects


Laker oa current status
Laker.oa Current Status

  • Can open GDSII imported DB and edit with most of Laker level-2 (polygon editor) functions.

    • Rule-Driven

    • P2P

    • Net Tracer, Short Locator

    • iDRC

  • Can open DEF imported DB and view route segment and via.
