TEST Means HW/SW Facilities to support A/C equipment,Subsystem or system verification&validation process across product life-cycle

  • Verification means “ Are we building the

product right?” It involves checking that the product conforms to its specification

  • Validation means “ Are we building the

right product?” It involves checking that the product as implemented meets the expectations of the product customer

SEAS Simulations Build (II)

Bench signals The SEAS user API gives the user the capability to associate Bench signals with simulation variables Simulation variables

Main procedure, it instantiates a Simulation process class Signal_process-Simulation It implements the simulation process class Simulation Process (spec and body) It is a skeleton for the user to implement the simulation functionality (INIT, EXEC and STOP) Interface files It provides signals and IFUs-HW objects pointers to perform direct IO access to HW interfaces. Object copies are serialized from server process by using ADA95 Annex E. It implements Get_Values and Put_Values functions Simulations have capability to call directly any HW interfaces API’s functions for specific board handling Binding package to COTS API´s given in C or C++

Conclusion

Test System built around GNATPRO-Suite :

  • Ada95 for SEAS Core SW using class wide programming for Processes,

Signals, HW Interfaces, Scaling

  • Ada95 for Mission System simulations repertoire
  • GTKADA for HMI and for special synoptic like mission scenarios, radar

display simulations

  • XMLADA for test system definitions Bench HW/SW definition
  • Distributed Ada for shared memories, RPC , data, types and objects

distribution

  • GPS to create simulations
  • High Flexibility for integration of non Ada SW like FORTRAN,C, C++ API’s

We consider using the provided solution by GNATPRO suite, as the core to develop such complex hybrid systems, with large life cycle like test systems for A/C V&V, offered big advantages.
