Creating a new Repository and Project Tutorial Series: Spec-TRACER Requirements Lifecycle Management A Spec-TRACER Repository contains complete information of all projects and users. In the avionics industry, a Repository can be considered as the entire program for the system hardware where the system hardware consists of multiple FPGAs. Each FPGA design can then be considered as a Spec-TRACER Project. Within a repository, Users and User Groups are also defined. Users are assigned to specific User Groups of the projects in the repository, so the same user is allowed to have different roles in the different projects in the repository.
