Check for blocks not recommended for secure coding standards

Check ID: mathworks.security.BlockSupport

Identify blocks not recommended for compliance with secure coding standards.

Description

Following the recommendations of this check increases the likelihood of generating code that complies with CERT C, CWE, ISO/IEC TS 17961 secure coding standards.

Available with Embedded Coder^® and Simulink^® Check™.

Results and Recommended Actions

Condition	Recommended Action
Lookup Table blocks using cubic spline interpolation or extrapolation methods were found in the model or subsystem. Specific blocks are: 1-D Lookup Table 2-D Lookup Table n-D Lookup Table	Consider other interpolation and extrapolation methods for the Lookup Table blocks.
Deprecated Lookup Table blocks were found in the model or subsystem. Specific blocks are: Lookup Table Lookup Table (2-D)	Consider replacing the deprecated Lookup Table blocks.
S-Function Builder blocks were found in the model or subsystem.	Consider replacing the S-Function Builder blocks with blocks recommended for production.
From Workspace blocks were found in the model or subsystem	Consider replacing the From Workspace blocks with blocks recommended for production.
String blocks were found in the model or subsystem. Specific blocks are: Compose String Scan String String to Single String to Double To String	Consider replacing the String blocks with blocks recommended for production.

Capabilities and Limitations
