Probability of latching single event upset errors in VLSI circuits
… on the effect of transient faults on flip-flops rather than combinational logic. This is due to several reasons. First, transient faults, also known as Single Event Upsets (SEU), were first observed in memory circuits located on board satellites. Second, an SEU can leave a lasting …

A novel approach to embedding memory with crosstalk logic circuits for high performance applications
… elements of computing is the memory element. Flip-flops form an integral part of a System-on-Chip (SoC) and consume most of the area on the die. To meet the high-speed performance demands by data-intensive applications like artificial intelligence, cloud computing, and machine learning, we …

Spatial Voting Models: A Dynamical Systems Approach
… points mirrored findings in previous research. Flip-Flop and Noncompetitive points, however, identified sub-optimal candidate positions that might arise during an election. Flip-flop points appeared to highlight situations in which candidates oscillated between trying to outmaneuver their …

Susceptibility evaluation of combinational logic in VLSI circuits
… attempts to determine the affect of an SEU on a flip-flop which might lay at the end of a chain of combinational logic gates. In this way, the concept of an upset window, as it pertains to different types of logic gates is introduced. The results of the simulations carried out on various blocks …

Selection of flip-flops for partial scan design
… for sequential circuits. As only a portion of flip-flops are incorporated into a scan chain in partial scan design, scan flip-flop selection constitutes a key procedure in partial scan. In this thesis, we propose a new way of selecting scan flip-flops, the Extended Tracking Algorithm (ETA). ETA …

Clock gatting for latch based design
… que impiden que la señal de clk llegue a los Flip-Flop cuando el valor de la salida de estos no se espera que cambie. Los diseños basados en Latch, que si bien no son tan utilizados como los diseños basados en Flip-Flop debido a sus complejidades adicionales, todavía son utilizados gracias a …

Untestable Fault Identification Using Implications
… could be either a Primary output (PO) or a scan flip-flop. The current state-of-the-art automatic test pattern generators (ATPGs) spend a lot of time in trying to generate a test sequence for the detection of untestable faults, before aborting on them, or identifying them as untestable, given …

Magnesium Diboride Superconducting Devices and Circuits
… circuits were designed and tested. A toggle flip flop (TFF) operating as a frequency divider was developed. The TFF design consisted of a Josephson transmission line, a splitter, and an interferometer (a DC SQUID). The TFF utilized an improved designed, compared to previous all-MgB2 TFFs, and …

Investigating CO2 Adsorption Behavior in Metal-Organic Frameworks by Solid-state NMR
… MOFs. NMR results suggest that D2O undergoes a π-flip flop motion and a 4-site jumping motion in [Zn2(TRZ)2(NH2-BDC)]. Additionally, CO2 undergoes C2 hopping and C3 wobbling motion for both MOFs. Once single component adsorption was examined, co-adsorption of CO2 and water was also investigated …
