The VLSI circuit operation is very similar. If the driving cell is strong, it takes less delay and changes the output quicker than a weaker driver, which produces a sluggish response and takes longer to produce
Present invention suggests a method to extract accurate value and time domain of the current in the VLSI circuit, which is almost impossible by the conventional methods. Conventional approaches take the current of a cell as a constant average value extracted by power consumption, which makes ...
CMOS technology continues to drive the reduction in switching delay and power while improving area density. However, the transistor miniaturization also introduces many new challenges in Very Large Integrated (VLSI) circuit design, such as sensitivity to process variations, increasing transistor leakag...
In VLSI chip design flow, Static Timing Analysis (STA) is used for fast and accurate analysis of data-path delay. This process is fast because delay is picked from Look Up Tables (LUT) rather than conventional SPICE simulations. But accuracy of this method depends upon the underlying delay ...
Results observed the effects on delay, power, and noise margins, showing that process variability can introduce up to 100% of power deviation. Read Static Noise Margin (RSNM) presents about 20% of deviation under process variability and the cell noise robustness is reduced dramatically in worst ...
标准单元(Standard Cell)是一般数字VLSI设计中的基本组件。整个数字电路逻辑设计,在逻辑综合与工艺映射中(这两者概念请参考),会被替换成一堆互相连接的标准单元。常见的Standard Cell有基本逻辑门(与、或、与非、亦或...)、Flip-Flop寄存器、MUX多路选择器、加法器、时钟单元、延时缓冲(Delay Buffer)等等。基于这些标...
