This also applies to dispensing limit ed precious resources available such as lower-vt, wider wires. However, it is possible that more-critical regions may be closed easily by logic rede sign or more accurate boundary assertions while less-critical regions may not have such options and struggle. Such less-critical regions may need to be prioritized higher during Physical Synthesis. This is especially helpf ul earlier in the design cycle, to evaluate viability of design timing clo sure. Priority Synthesis feature is aimed at addressing this need. \nThis work focuses on significantly enhancing priority infrastructure and improv ing timing QOR. Highlights include infrastructure that allows identificati on of priority regions along with customization of precious resources earm arked exclusively for such regions. In addition, special optimization step s that target priority regions have been created. Among other things such steps ”steal” or redirect routing resource from non-priority regions to en hance priority regions, when appropriate. Based on early user feedback, th e timing in priority regions for a challenging design in the field is almo st closed with Priority synthesis feature potentially paving way for cycle time reduction. This concept is being currently extended to routing steps .\n\nVirtual Program: Presented In-Person END:VEVENT END:VCALENDAR
