Today , consumers are no longer satisfied with only voice communication , but demand for more services . this pushes the development of mobile terminal technology and the functions of the mobile terminals are becoming richer 現(xiàn)在,用戶(hù)已不滿足僅僅實(shí)現(xiàn)語(yǔ)音通信服務(wù),對(duì)移動(dòng)終端的要求越來(lái)越高,促使移動(dòng)業(yè)務(wù)推陳出新、日漸豐富,移動(dòng)終端功能趨向多樣化。
In deep sub - micron technology , the scale of integration and the degree of complexity of circuit increase rapidly , it is necessary and feasible to adopt non - manhattan model for detailed routing in vlsi physical design . aiming at the current pop point a novel non - manhattan otc router is proposed in section 4 . according to the routing algorithm of channel area the new otc router selects nets on cell by using net segment valid controlling column technology , deep searching to column density technology and utilization of vacant terminals technology 結(jié)合通道區(qū)域所用非曼哈頓布線算法的特點(diǎn),通過(guò)采用線網(wǎng)段有效控制列技術(shù)、列密度深度探測(cè)技術(shù)及空端利用技術(shù)對(duì)單元區(qū)可布線網(wǎng)進(jìn)行有效選擇,成功地實(shí)現(xiàn)了該非曼哈頓單元上布線算法,并將其應(yīng)用于一些經(jīng)典的benchmark中,和目前文獻(xiàn)中現(xiàn)有算法相比取得了更優(yōu)的布線結(jié)果。
