2、TSV利用率。在算法中引入全局次優(yōu)極值對粒子進(jìn)行指導(dǎo),提高全局搜索能力;并通過自適應(yīng)參數(shù)調(diào)整策略增加種群多樣性,從而改善粒子搜索的停滯現(xiàn)象。以國際標(biāo)準(zhǔn)測試集ITC'02中的電路作為仿真對象,仿真結(jié)果表明,算法能夠有效地完成在多約束下對TSV位置的尋優(yōu)并合理分配通信資源,縮短了測試時間,提高了TSV利用率。關(guān)鍵詞:三維片上網(wǎng)絡(luò);測試規(guī)劃;硅通孔技術(shù);多約束;離散粒子群算法中圖分類號:TH701文獻(xiàn)標(biāo)識碼:A國家標(biāo)準(zhǔn)學(xué)科分類代碼:510.5099Cooperativetestschedulingof3DNoCundermultipleconstraintsbasedonth
