Now they are readily accepted throughout industry. The reasons for their current popularity are the rapidly increasing costs of labor and the seemingly declining productivity of todays workers. In addition, robots today are credited for additional product and quality improvements not seriously considered in the past. Benefits similar to those that have long been attributes associated with hard automation. This paper looks at robotics from a users viewpoint and addresses some of the benefits and concerns attributable to their use. To this end, this paper will describe several applications that are currently used in production with results relative to production gains, side benefits and operator acceptance.","PeriodicalId":290739,"journal":{"name":"19th Design Automation Conference","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130454433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system has knowledge about the technology adopted and can accommodate various know-how and design constraints to support the designer's tasks of PCB partition and logic synthesis. As a result, it greatly relieves designers from tedious tasks and makes it possible to explore alternative designs.","PeriodicalId":290739,"journal":{"name":"19th Design Automation Conference","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131641849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we represent a pattern or shape of a route by a sequence of symbols representing directions of constituent line segments. Then, we investigate a condition that a sequence of symbols represents a valid pattern. We also count all valid patterns. Given two points, we can specify any route between them by a pattern of the route and lengths of segments. If we vary their lengths as parameters, then we can generate various routes. Therefore, the parametric pattern router with all possible patterns can always find a path between two points if one exists. The user of the router may define a set of admissible routing patterns according to circumstances.","PeriodicalId":290739,"journal":{"name":"19th Design Automation Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123830466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An extended cell admissibility is defined for continuous design rules in coarse rectangular grids. Combined hardware and software design strategies are applied towards the definition of data structures and their kernel primitives for automatic routing. The hardware architecture and the implementation of specific structures are discussed. The resulting extended routing unit is used in a CAD system. Thus the throughput of the iterative router is improved by a factor of 5 compared to the equivalent software process. Finally the architecture of a high speed stand-alone routing processor is presented.","PeriodicalId":290739,"journal":{"name":"19th Design Automation Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115252851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
