Delay dependence on input patterns nand gate
http://access.ee.ntu.edu.tw/course/VLSI_design_92first/ppt/lecture_10_chapter6-1_PartI_05-15-2003.pdf WebThe hardest min-delay problems occur in paths that could be either fast or slow in a data-dependent fashion. For example, a path built from a series of nand gates may be fast when both parallel pmos transistors turn on and slower when only one pmos transistor turns on. A path using wide domino or gates is even more sensitive to input patterns ...

WebDelay in a Logic Gate Express delays in process-independent unit Delay has two components: d = f + p f: effort delay = gh (a.k.a. stage effort) – Again has two components g: logical effort – Measures relative ability of gate to deliver current – g ≡1 for inverter h: electrical effort = C out / C in – Ratio of output to input capacitance Webthe NAND output and the INV input as shown below. Also, add wires on the NAND inputs and INV output so that we can place pins on the other end of the wires. When adding wires, click once to start a wire or place a node without ending the wire. To end a wire, double-click or single-clicking on a component terminal (e.g., gate input/output, pin) .
