MVPI supervision software


  • Operator friendly production machine supervision software
  • Easily customisable to fit any machine
  • High performance achieved thanks to its well structured architecture





The main features of the MVPi software are :

  • Synchronisation between the execution of test programs within the MP300 and the state of the machine
  • Ease of use
  • Simplicity and stability
  • Complete control of the link with the MP300
  • Adaptability to any production machine
  • Possibility to interface with an external HSM (Hardware Security Modules)
  • Presence of an offline mode, that allows to run test program without interfacing the machine

This piece of software is designed to run inside production machines integrating MP300 production tools.

  • OS loading
  • Personalisation
Access to data server done through :
  • TCP/IP
  • RS 232
  • Data bases (MS SQL server, MySql, Oracle, ...)
  • Data file
Tests can be run using the following patterns
  • All in parallel
  • In sequence
  • Using checkerboard patterns
Logfile generation
  • Can be enabled or disabled
  • Content is defined inside test application

MVPi is able to handle up to 32 test heads at the same time, but upgrades are easily possible.

 
The main window of MVPi

 

Statistics are available, either separated between all test heads, or displayed for the whole system

 
Here, the number of failures, and the reason of the failure, for the head 3

 

More statistics are available, showing the current test time, as well as the average one.

 
Here, total of good, bad chips, and the testing time

 

As smartcards are being produced, logfiles are also generated, that allow to keep track of the produced components. The content of this logfile is controlled by the user.
