Project Overview
The overarching project is a portion of the virtual lab,
under CHASE
This goal of this project is to create a board with a webinterface that will detect out of current to determine if
DUT is counterfeit
The CDEB project will actually contain two interlinked
projects
1) Continuation of the first CDEB by last year’s
senior design team
2) A web interface and server dedicated to
collecting chip information from customers

Module 1
The specific types of
counterfeit chips to be
detected are recycled and
out of spec copies
Our team assumes that
recycled chips should
have noticeable wear
characteristics
In this case we are
attempting to detect out
of spec transient and
leakage current

Module 1
The current board in
use is the firstgeneration board,
designed by last year’s
senior design team
The current design
calls for the chip in
question to first be
programmed
Computer
USB UART
LAN Connection
An FPGA sends a test
signal to the board
DC power and AC
clock supplies are
controlled by a
computer

Module 1
The board currently
is designed for the
8051
For our project we
will continue to test
the 8051
Our goal is to order
more boards, 10 in
total and run python
code to switch
between boards

Module 2
Module 2 is the proposed
web interface
The web interface will
include a loggable
website which will allow
data, a server that holds
log information, data
upload, and will hold the
output data gathered from
the oscilloscope and
compiled by the computer
All Rights Reserved
6
Module 2
The web interface must
gather the following
information:
General customer
stats, name address,
email, etc.
Pin count and
information
Chip name, model #
Voltage specifications
Test code, with pin
directions
All Rights Reserved
7
Module 2
The server must:
Hold the customer
information
Send the engineer
relevant information
Run the Python code
when the engineer
launches the program
Connect to the
hardware modules
and hold the resulting
excel files
