System Package

• Program package is divided in four parts
• GUI
• eSNACC modified program
• Code generator
• Converter

4
Functional Requirement 1/4

• To develop program package that can generate
  specific converters without need of any
  additional programming

5
Functional requirements 2/4

• ASN.1 grammar view
• The grammar should be presented as a tree view on
  the left side of the GUI
• ASN.1 grammar entities selection
• Users can select checkboxes of entities in tree
  presentation that they want to have in output CSV
  file

6
Functional requirements 3/4

• Output formats
• The right-click on entity in the tree view should
  display a list of possible output formats (text
  string, BCD string, hexadecimal string, decimal
  number, etc.)
• eSNACC
• eSNACC modified program have to generate ANS.1
  decoding routines that uses selected entities in
  the GUI

7
Functional requirements 4/4

• Code generator
• The generated program should be compliable on any
  platform (UNIX, Windows, Mac OS) with a standard
  ANSI C compiler
• Converter
• Converter should accept the following command
  line parameters
• asn2csv i ltinputASN.1 binary filegt -o ltoutput
  CSV filegt -d

8
Non-functional requirements

• System
• System should be stable, without bugs
• Debugging and tracing information
• GUI
• GUI should be user friendly and easy to use
• Converter performace
• Converter should be fast as possible
