Objective:
To obtain a challenging intern/full-time R&D position in the field of
design automation, software & GUI design, programming sup****t, device
characterization and verification, and behavioral modeling and
simulation.
Education:
M.S. student in Electrical Engineering, University of Arkansas,
Fayetteville Aug 2008
(Expected)
B.S. in Automation Engineering, University of Electronic Sci & Tech of
China, Chengdu, China
GPA:
3.64/4.0
June 2006
Research Experience:
Research Assistant MSCAD Lab, University of Arkansas,
Fayetteville August 2006-
Present
Responsible for the development of a model characterization and
validation tool called Certify. It is a relatively lightweight,
flowchart oriented tool that allows the user to capture model
characterization recipes, save and reuse them (including simulator
settings), im****t data, and perform parameter extraction and curve
fitting. Certify has been integrated with Synopsys Saber and Cadence
Spectre simulators, and it is is able to use a "simulator-in-the-loop"
approach for optimization with several optimization algorithms.
Certify tool is consists of the following three parts:
Characterization recipe capture: consists of test bench editor and
experiment editor. Users are able to draw flow charts to im****t test
benches/model files and set up analyses. Developed in Python and Qt/
PyQt GUI toolkit. Database is designed using XML format.
Optimizer for Saber: Users are able to select and set up optimization
algorithms, perform the optimization, and get the best fitting set of
parameter values for behavioral or device models. It will also show
graphs of both physical measured data and simulated results for
comparison. Developed in AIM scripting language. AIM is a superset of
Tcl/Tk scripting language and is able to control all Saber
applications. Saber & CosmosScope are used for this application.
Optimizer for Spectre: The same function as its Saber counterpart.
Developed in OCEAN/SKILL scripting language. The SKILL language is
often used with most Virtuoso products. In Certify, it controls the
Virtuoso Analog Design Environment especially with the Spectre
simulator.
