X-STEP™ is a test system that covers all design phases from early R&D to field installations. With X-STEP™, ecosystem partners can exchange authentic traffic information and views of the standards and specifications in an executable format. This leaves no room for interpretation, and all partners can be sure to base their development and verification on identical requirements. Potential conflicts are detected well in advance, preventing them from disturbing system integration. Interoperability becomes the key aspect in the way that individual products are designed and verified.
