Adalah menjadi trend untuk mempertimbangkan integriti bekalan kuasa pada peringkat awal untuk meningkatkan kualiti reka bentuk. Secara khusus, proses pelan lantai diubah suai untuk menambah baik bekalan kuasa juga. Dalam proses pelan lantai yang diubah suai, kedua-dua pelan lantai dan rangkaian kuasa/tanah (P/G) dilaraskan untuk mencari pelan lantai yang optimum serta bekalan kuasa yang paling teguh. Dalam makalah ini, kami mencadangkan algoritma baru untuk melaksanakan perancangan lantai yang diubah suai ini. Kaedah analisis baharu dicadangkan untuk menganggarkan penurunan voltan manakala pelan lantai sentiasa berubah-ubah. Kaedah anggaran susut voltan analitikal yang pantas ini dipalamkan ke dalam perancang lantai yang diubah suai untuk mempercepatkan keseluruhan proses perancangan lantai. Berbanding dengan kaedah sebelumnya, algoritma kami boleh mencari pelan lantai yang optimum dengan mengambil kira integriti bekalan kuasa dengan lebih cekap dan oleh itu membawa kepada hasil yang lebih baik. Tambahan pula, kertas ini juga mencadangkan kaedah heuristik baru untuk mengoptimumkan topologi rangkaian P/G. Algoritma pengoptimuman ini boleh membina sistem bekalan kuasa yang lebih mantap. Keputusan eksperimen menunjukkan kaedah itu boleh mempercepatkan proses perancangan lantai sedar IR-drop sebanyak kira-kira 10 kali dan mengurangkan kawasan penghalaan rangkaian P/G sambil mengekalkan kualiti pelan lantai dan integriti bekalan kuasa.

Abstract: It's a trend to consider the power supply integrity at early stage to improve the design quality. Specifically, floorplanning process is modified to improve the power supply as well. In the modified floorplanning process, both the floorplan and power/ground (P/G) network are adjusted to search for optimal floorplan as well as the most robust power supply. In this paper, we propose a novel algorithm to carry out this modified floorplanning. A new analytical method is proposed to estimate the voltage drop while the floorplan is varying constantly. This fast analytical voltage drop estimating method is plugged into the modified floorplanner to speed up the whole floorplanning process. Compared with previous methods, our algorithm can search for the optimal floorplan with consideration of power supply integrity more efficiently and therefore leads to better results. Furthermore, this paper also proposes a novel heuristic method to optimize the topology of P/G network. This optimization algorithm could construct a more robust power supply system. Experimental results show the method can speedup the IR-drop aware floorplanning process by about 10 times and reduce the routing area of P/G network while maintaining the floorplan quality and power supply integrity.
