Abstract
【解決手段】 論理合成及び配置配線に用いるスタンダードセルを、出力側の論理回路と入力側の論理回路とから構成し、出力側の論理回路の駆動能力を大きくし、入力側の論理回路のゲート入力容量を小さくする。このような構成のスタンダードセルにすることで、機能回路における遅延時間のうち、ゲート遅延の占める割合を相対的に高めることができる。従って、各スタンダードセルのゲート遅延を精度良く見積もれれば、配置配線後の配線容量を事前に正確に見積もれなくても、論理合成の時点で動作周波数を精度良く求めることができる。つまり、論理合成結果の信頼性が向上し、論理合成と自動配置配線とを繰り返す必要が無くなり、設計期間を短縮することができる。
