the digital integrated circuits, a circuit under the general-synchronous framework where zero clock skew is not assumed is expected to achieve a better performance compared with a circuit under the complete-synchronous framework where zero clock skew is assumed. The minimum clock period under general-synchronous framework is not bounded by a maximum delay path but by the delay paths on a critical cycle. It is crucial to synthesize a circuit under the general synchronous framework in order to obtain a better circuit efficiently. In this paper, we propose a circuit synthesis method to obtain a better circuit in general-synchronous framework under the assumption that any clock scheduling can be realized. The proposed method can be easily implemented by a commercial tool. The validity of our proposed method is shown by comparing to the method under complete-synchronous framework.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2019-01-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"2019-SLDM-186"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":194206,"links":{}}
