Systems and methods transform a user-defined program flowchart into executable code. A graphical authoring / import interface persists the flowchart as a typed graph of nodes and edges. A knowledge base is built by ingesting user-authorized schemas, code repositories, and API specifications, normalizing discovered elements as term objects with types and aliases. For nodes containing natural-language or pseudocode text, a domain-specific selection model, constrained to the knowledge base, selects canonical domain terms. The typed graph and selections are lowered to an intermediate representation and compiled into target-specific code including parameterized data-access statements and API invocations. The system synthesizes and executes unit and path tests, then assembles a deployable runtime package with a configuration manifest identifying dependencies, secrets, endpoints, and health probes. The package may be deployed as an rApp in a Service Management and Orchestration environment to analyze RAN KPIs and issue closed-loop control actions.

The invention relates to the technical field of integrated circuit design, in particular to a built-in test system based on an AXI interface, the system performs data path test through a test master module and a test slave module in an AXI test module, the test master module takes over a data path sent to a downstream module, and the test slave module takes over the data path sent to the downstream module.
