Current Status
Progress reportReleased Stylus: 1 minor, 2 major [June 2002]
Offering text editor syntax files [open source]• http://www.inovys.com/login/STIL-mode.el• http://www.inovys.com/login/STIL.vim
SuccessesVerified STIL customer patterns from FastScan
Verified STIL customer patterns from TetraMAX
Current Status (continued)
Technical issuesNo 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
Contribute real usage experience
Sandbox dot committee extensions
Conform to final balloted specification
Conclusions:
Inovys supports STIL natively today
STIL flow working at major customer(s)
Accelerates fail data feedback to EDA
Fully Committed to STIL
