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
