Current status l.jpg

Current Status

  • Progress report

    • Released Stylus: 1 minor, 2 major [June 2002]

    • Offering text editor syntax files [open source]

      • http://www.inovys.com/login/STIL-mode.el

  • Successes

    • Verified STIL customer patterns from FastScan

    • Verified STIL customer patterns from TetraMAX


Current status continued l.jpg

Current Status (continued)

  • Technical issues

    • No showstoppers

  • Limitations Specific to STIL

    • Practical considerations in actual use, e.g.

      • Name reuse/conflicts combining runs

      • Common to see forward referencing error

      • and more…


Future plans l.jpg

Future plans

  • Contribute real usage experience

  • Sandbox dot committee extensions

  • Conform to final balloted specification


Conclusions l.jpg

Conclusions:

  • Inovys supports STIL natively today

  • STIL flow working at major customer(s)

  • Accelerates fail data feedback to EDA
