# Spectra CX Product Line Management This optional feature for the standard Spectra CX product supports modeling of a radio family within Spectra CX. This feature provides architects with the ability to identify variation points in the product line based on a single “base” model. Variation points allow product engineers to specify product configurations, which are used to generate standard Spectra CX models for each product variant. # Modeling Product Lines Spectra CX supports modeling of Software Communications Architecture (SCA) applications (waveforms) and platforms (nodes or assemblies of nodes), and verification of compliance with the SCA specification. From a CX model the user is able to generate the full SCA domain profile, the set of XML descriptors, for the applications and nodes. Radio manufacturers need to produce variants of their SCA applications and platforms to support different configurations of the radio set. Developers also need to manage development, test, and production versions of their radio components. Currently radio architects and developers use the Spectra CX model management capabilities to produce and manage complete models for each variant. The Product Line Management feature adds new modeling elements, Variation Points, to Spectra CX. Product line architects can use variation points to identify the product variations for the components instances, ports, and properties of their application or platform. This enables them to use a single model for the entire product line. # Product Line Model # Variation Points Identify one or more locations in the product line model where a variation may occur. Variation points come in multiple forms providing the ability to identify optional elements, parameterize the values of attributes, parameterize the settings of an element, and other elementspecific options. Variation points can be created on applications and platforms; components and devices; properties; implementations; and ports. A single variation point may be used to constrain multiple model elements of the same type. This allows an architect to simplify the model by logically grouping variation points. # Variation Point Model Generated from the product line model it enumerates all of the variation points making it easier to specify product configurations. ![Based on the provided image, here is the accurate and concise description of the flowchart/block diagram:\n\n**Labeled Blocks:**\n\n* **ExecutableDevice**: A label positioned above the top-left block.\n* **ModemInterface**: A blue rectangular block labeled 'ModemInterface'.\n* **Modem**: A blue rectangular block labeled 'Modem' containing the following attributes:\n * `processor_name : processor_name`\n * `os_name : os_name`\n * `KIPS : KIPS`\n * `Throughput : Throughput`\n * `os_version : os_version`\n* **KIPS**: A pink note block labeled 'KIPS' with the text `«VariationPointWithValue»` below it.\n* **Throughput**: A pink note block labeled 'Throughput' with the text `«VariationPointWithValue»` below it.\n* **Modem**: A pink note block labeled 'Modem' with the text `«VariationPointWithSettings»` below it.\n\n**Connections:**\n\n* A solid line with a hollow triangle arrow connects the **Modem** block (bottom left) to the **ModemInterface** block (top left), indicating a generalization relationship.\n* A dashed line connects the **Modem** block (bottom left) to the **Modem** note block (bottom right).\n* A small circle connects to the top center of the **ModemInterface** block.\n* A small arrow points to the right from the right side of the **ModemInterface** block.](.spectra-cx-plm/9281556632631e88f1a87f74d4e153c802a2ff4fc622d58193bc217893915f60.jpg) # Product Configuration Editor Using the generated variation point model a product engineer can create specific configurations of the base model where they include / exclude optional elements and provide values and settings for the parameterized variation points. # Product Configuration Models Once a product configuration has been engineered and validated, users can generate a new Spectra CX model that takes into account the specified configuration values. From this model artifact, the user will be able to generate the SCA domain profile and other Spectra CX generated SCA artifacts (C/C++ code, unit tests), and deploy and test their application configuration on the platform variant. # Complementary SDR Products Spectra CX Product Line Management is part of the most complete family of Software Defined Radio (SDR) products and technologies designed to support all of your SCA SDR development needs. # Expect Professional Services ADLINK offers a complete suite of training courses on the SCA and SDR technologies and their implementation using ADLINK’s Spectra SDR products.
