VME C-Model Interface is a dramatic new approach in developing
digital functional test programs. CMI is a complete software
interface program designed to develop and modify test
programs in a non-simulated environment directly on the
Device Under Test (DUT).
using plug-in style bus interface modules the user can
quickly interact with the DUT using standard type interfaces
such as VME, RS232, GBIB, PCI, 1553 or any custom interface
can quickly be developed. This approach drastically
reduces development and integration time.
Integrated Test Solutions has demonstrated the powerful
capabilities of this new approach from simple to very
complex circuit card assemblies including Commercial
Off the shelve (COTS) cards.
This application program interface (API) uses the Digital
Test Instrument (DTI) as a VMEbus or other interface
sub system. The API allows the DTI to communicate with
circuit card assemblies (CCA's) using standard communication
protocols. The API emulates bus activity via an internal
state machine and manifests the bus activity dynamically
through the digital test instrument. The API will provides
test developers with a high level programming environment
to develop or re-host tests. Advanced test sets will
become more feasible due to the APIs ability to be used
in both C and C++ based development environments.
