| 摘 要： | 对IR-drop和EM现象进行了解释和分析,结合地面数字电视基带调制器芯片的设计,将标准单元区域简化为电源电阻网络进行建模,根据模型计算出最大电压降,在保证最大电压降区域能够正常工作的基础上,简单有效地设计了标准单元模块区域的电源网络,最后在考虑到宏模块电源环压降的前提下,将宏模块区域转化成标准单元区域进行建模,完成了整个芯片的电源网络设计.此方法运用于早期布局,确保电源分配的可靠性,提高设计效率,通过地面数字电视多媒体广播的全模式发射端芯片的流片成功和功能的实现,证明了该方法的实用性和有效性.

| Abstract: | The influencing factors and the reason of IR-drop and electromigration were analysed.Taking the design of power/ground distribution network for transmitter of digital terrestrial television multimedia broadcast for an example,power/ground distribution network which ensured the normal operation in maximum IR-drop area was built around standard cells.Maximum IR-drop estimation was made by treating standard cell area as power/ground and resistor network.Finally,macro area was converted to standard cell area to... |
