# Spectra CX – Development Tool for SCA/SDR Developers

Spectra CX4 is a model-driven development tool that simplifies, accelerates, and validates a significant proportion of the Software Defined Radio (SDR) Software Communications Architecture (SCA) development process. Spectra CX4 validates SCA 4.1 compliance at the architectural level and generates correct-by-construction SCA compliant artifacts, such as: XML descriptor files and C++ source code. Spectra CX enables SCA 4.1 and non-SCA software aspects to be developed together, integrated early, and thoroughly tested. Spectra CX4 also reduces development risk due to its consistent model-based approach. Together the above benefits result in faster time-to-market, lower costs, better software quality, and superior compliance for all SCA 4.1 waveform and platform code developed with Spectra CX4.

# Model with Spectra CX

# Benefits from complete SCA 4.1 system modeling – components, applications, nodes platforms, deployments

Spectra CX4 provides visual modeling for all project stakeholders. Powerful visual representation of SCA concepts ensures that every project team member has a global understanding of the system and can produce correct SCA 4.1 artifacts. Spectra CX4 supports modeling of components, applications (waveforms), devices, platforms, and deployment of waveforms on target platforms. With SCA systems being dependant on multiple devices having enough resources and capacity to run the intended applications, it is vital that all applications are modeled with their planned platform.

Modeling deployments throughout the development cycle with Spectra CX4 allows the project team to specify and track the deployment explicitly, and ensure that untested deployments are never accidentally deployed.

# Validate with Spectra CX

# De-risk projects by validating early on, and throughout the development cycle

Spectra CX4 allows developers to produce SCA 4.1 compliant software from day one. Validation is built right into Spectra CX4 providing automatic identification of errors in SCA 4.1 compliant radio platforms and waveform applications. In addition to checking the syntax of the Document Type Definition (DTD), Spectra CX4 validates the semantic correctness of the model. Errors are presented along with a hyperlink to the model construct that violates the SCA standard. Spectra CX also provides suggestions for correcting the violation.

Many SCA projects involve the integration of legacy and 3rd party waveforms. Spectra CX4 facilitates integration by allowing developers to migrate existing SCA 2.2.x models, validate them against the SCA standard for correctness, and assemble them into a complete and valid application or platform. Spectra CX4 provides a complete development environment for SCA 4.1 compliant software, validating at every stage, up to and including deployment.

• Automatically validate for SCA 4.1 compliance — applications (waveforms), platforms, and deployments
• Validate model for syntactical and semantic correctness
•
• Guidance on resolving SCA 4.1 violations with links to the cause and suggested modifications

# Generate with Spectra CX

# Accelerate and de-risk SCA development by generating correct-by-construction SCA artifacts

Spectra CX4 provides push-button generation of correct-by-construction descriptor files and documentation. By automatically generating the complete set of SCA compliant descriptor files, i.e. the entire SCA Domain Profile, development time can be reduced from months to days. Generating documentation improves communication between team members. Documentation generation through Spectra CX4 is completely customizable. Developers can produce documentation relating to a specific view, for example, a list of all components in the waveform or a description of an intended deployment.

Automated generation of code implementing SCA 4.1 component structure is provided through Spectra CX4’s C++ Code Generator. It automates the production of both SCA application code and SCA device code. Device code abstracts the physical hardware in accordance with the SCA 4.1 specification. Automating the generation of this code benefits both developers of SCA 4.1 compliant radio platforms and developers needing to modify an SCA 4.1 compliant radio platform, allowing them to make changes to their hardware while ensuring continuous adherence to the SCA 4.1 specification.

RTCORBA concepts can be modeled and C++ generation is supported in Spectra CX4.

UML generation of classes representing existing generated source code is supported in Spectra CX4. These UML classes can be used for documentation purposes or to add relationships to other C++ classes which are used during Spectra CX4 C++ generation.

• Push-button generation of the complete set of SCA XML descriptors
• Extensible code generators
• Generates SCA structural code in C++
• Build environment generation
• UML class generation representing generated C++ source code

Develop with SpectraCX

# Execute with Spectra CX

Monitor the component system on its actual target, with the platform running multiple applications for complete testing

In an SCA radio, the actual deployment of software components to hardware devices is done at system initialization time. For this reason, developers require features that enable them to connect to the SCA Core Framework (CF) to thoroughly test their application running live. In addition to features for SCA development, the Spectra CX environment contains comprehensive features allowing developers to quickly and easily test and debug their components and applications.

Also available is an SDR Development Suite comprising Spectra CX4 plus a complete SCA 4.1 operating environment (Spectra CF and Spectra CDB) designed to run on a PC host. Users can observe their applications deployed on a commercial-grade SCA CF in record time.

• Support for development hosts and embedded targets
• Use design model to force particular deployment
