Alternative Timing in Digital Logic
Conover, George (2015-12-14)
For many decades using a system clock has been the go-to method of timing circuits. CPUs in particular have been at least partially defined by the speed of their clock. As technology moves forward, this is proving more and ...
Built-in Self-Test and Calibration of Mixed-signal Devices
Jiang, Wei (2011-05-05)
Wide adoption of deep sub-micron and nanoscale technologies in the modern semiconductor industry is resulted in very large complex mixed-signal devices. It has then become more difficult to estimate and control device ...
Characterizing Processors for Time and Energy Optimization
Goyal, Harshit (2016-08-05)
Energy and performance are important aspects of microprocessors and their verification and management require, measurement, estimation and analysis and these aspects are discussed through this research. A processor executes ...
Controlled Transition Density Based Power Constrained Scan-BIST with Reduced Test Time
Rashid, Farhana (2012-03-08)
Controlling power dissipation in large circuits during test sessions is one of the major concerns in VLSI testing. The reason behind the high power dissipation during test is because unlike normal mode operation of the ...
DC Parametric Test and IDDQ Test Using Advantest T2000 ATE
Ding, Jialin (2015-07-24)
For purpose of improving quality of devices before shipping to customers, VLSI
testing methods have been developed to detect defective devices effectively by using
automatic test equipment (ATE). To test a chip properly, ...
Design of 3.33GHz CML Processor Datapath
Owahid, Abdullah (2012-04-17)
Almost a decade processor speed has been stuck at operating frequency 2-3GHz due to excessive power consumption of CMOS logic gate at higher frequency whereas predicted speed at present was 10-15GHz. This leads the idea ...
Detection and Mitigation of Electrostatic Pull-in Instability in MEMS Parallel Plate Actuators
Stevens, Colin (2013-07-19)
Electrostatic MEMS actuators are used in a wide variety of applications including micro-
machined gyroscopes, high speed mechanical switches, variable capacitors, and vibration
isolation devices. MEMS parallel plate ...
Diagnostic Test Generation for Path Delay Faults in a Scan Circuit
Luo, Zeshi (2015-07-24)
With the increase of density, speed and test time of large VLSI circuits, man-
ufacturers are eager to nd e cient ways to bring up yields. Often, VLSI testing
only tells if a circuit is faulty but is unable to locate ...
Diagnostic Test Generation for Transition Delay Faults Using a Two-Timeframe ATPG Model
Shi, Xiaolu (2015-07-24)
Determining the location and cause of a defect in a faulty circuit plays a vital role in VLSI testing. These are critical factors in boosting product quality and reducing manufacturing costs.
An automatic test generation ...
Diagnostic Test Pattern Generation and Fault Simulation for Stuck-at and Transition Faults
Zhang, Yu (2012-03-28)
In VLSI testing we need Automatic Test Pattern Generator (ATPG) to get input test vectors for Circuit Under Test (CUT). Generated test sets are usually compacted to save test time which is not good for failure diagnosis. ...
Digital Testing with Multi-Valued Logic Signals
Li, Baohu (2015-04-27)
The integrated circuit scaling has been following the Moore’s Law since 1965 [59, 60, 61]. Within these decades, researchers made great effort to shrink the transistor feature size and maximize the integration level. ...
Dual-Threshold Voltage Design of Sub-Threshold Circuits
Yao, Jia (2014-06-18)
Threshold voltage of MOSFET technology represents the value of the gate-source voltage
when the current in a MOS transistor starts to increase significantly since the conduction
layer just begins to appear. However, a ...
DVF4: A Dual Vth Feedback Type 4-Transistor Level Converter
Naishathrala Jayaraman, Karthik (2013-11-01)
Power dissipation in digital circuits has become one of the primary concerns in elec-
tronic design. With the increasing usage of portable devices, there are severe restrictions
being placed on the size, weight and power ...
An Efficient Transition Detector Exploiting Charge Sharing
Wang, Yu (2014-12-09)
Transition detectors have been widely employed for online error and metastability detection, including in Better-Than-Worst-Case (BTWC) timing design of microprocessors that are designed to allow occasional timing errors. ...
Exploiting Boundary Scan functions of FPGA on ATE
Zeng, Kunpeng (2015-07-21)
With the increase of integration density at chip level, the controllability and observability of defects become complicated, resulting in limited physical probe access to I/O pins. It is impractical to apply test stimulus ...
Finding Optimum Clock Frequencies for Aperiodic Test
Gunasekar, Sindhu (2014-04-29)
With scale down in technology, size and complexity of integrated circuits increase. The
scan method is the most popular technique of testing sequential circuits today. In this
method,
ip-
ops functionally form one or ...
High Sensitivity Signatures for Test and Diagnosis of Analog, Mixed-Signal and Radio-Frequency Circuits
Sindia, Suraj (2013-07-18)
The conventional approach, widely practiced in the industry today, for testing analog
circuits is to ensure that the circuit conforms to data-sheet limits on all its specifications.
However, such a specification based ...
