Statistical static timing analysis (SSTA) plays a key role in determining performance of the VLSI circuitsimplemented in state-of-the-art CMOS technology. A pre-requisite for employing SSTA is the characterizat
clk-to-q delay, library setup and library hold time. Lets begin with the interior of flip-flop When CLK is ‘low’, “Tr1” and “Tr3” turns ON. Hence, input ‘D’ is latched to output ‘Qm’ of negative latch. ‘Inv4, Inv6’ holds the ‘Q’ state of slave positive latch ...
Timing considerations are paramount when designing complex circuits such as very large-scale integrated (“VLSI”) circuits, which can be formed of many millions of cells. Flip-flops, in particular, require timing considerations related to setup and hold times. The setup time is the minimum ...

7. A CMOS driver as in claim 5, wherein said NFET and said additional NFET have width/length ratios which are approximately equal. Description:BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low power CMOS bus receiver with small setup time, and ...
Field of the Invention The present invention relates to a setup / hold time control circuit. In particular, in a VLSI chip structure that receives a signal from an external source, the external input signal and the input register of the VLSI chip use different clocks. Disclosed is a ...
Field of the Invention The present invention relates to a setup / hold time control circuit, and in particular, metastability of a signal transmitted when connecting registers using different clocks in a VLSI chip structure using multiple clocks. Disclosed are techniques for preventing the phenomenon....
