Introduction to Data Analysis
SEDana (Salland Engineering Data analysis application)
• SEDana Real-time is a plug-in module (DLL) for SEDana
(Salland Engineering Data analysis application).
• SEDana is a Fast, Easy, Practical tool for statistical
analysis of ATE (Automated Test Equipment) test data.

Real-time Module
DTC (Dynamic Test-Cell Controller)
• The Real-time Module communicates between a SPD
(Service Provider Daemon) and SEDana.
• The SPD is a process that receives the parametric data
from the Tester Daemons and makes it available for the
TCI (Test Cell Integration) modules.
• TCI is an umbrella term that describes a number of
products and services from Salland Engineering.

Real-time Module
SEDana (Analyzing Real-time Data)
• Implemented as plug-in module (DLL) for SEDana.
• Receives real-time data over network (TCP/IP).
• All SEDana features like tables, plots and text reports can
be used, as well as export real time data set to STDF file
on disk.
• Master Information Record (MIR) is received from tester
and contain information about job, tester, operator, etc.

Real-time Module
SPD (Service Provider Daemon)
• The Service provider gets the parametric data from each
individual tester.
• Real-time Module, SE-PROBE PAT are existing examples
of processes using this approach.
• Supported Teradyne tester platforms are:
• IG-XL™ (e.g. J750, FLEX™, UltraFLEX™)
• IMAGE™ (e.g. A5xx, Catalyst™)

Real-time Module
Storage of Real-time Data
• Real-time data is stored in the buffers of SEDana.
• SEDana uses these buffers to display plots, tables and text
reports.
• A real-time data set is growing when data is received from
the SPD.
• Real-time data sets can be duplicated.
