AUTOSAR Blockset / Classic Platform / Basic Software / Function Inhibition Manager (FiM)


For the AUTOSAR Classic Platform, the AUTOSAR standard defines important services as part of Basic Software (BSW) that runs in the AUTOSAR Runtime Environment (RTE). Examples include services provided by the Diagnostic Event Manager (Dem), the Function Inhibition Manager (FiM), and the NVRAM Manager (NvM). In the AUTOSAR RTE, AUTOSAR software components typically access BSW services by using client-server communication.

To support system-level modeling and simulation of AUTOSAR components and services, AUTOSAR Blockset provides an AUTOSAR Basic Software block library. The library contains preconfigured blocks for modeling component calls to AUTOSAR BSW services and reference implementations of the BSW services.

As defined in the AUTOSAR specification, the Function Inhibition Manager provides a control mechanism for selectively inhibiting (deactivating) function execution in software component runnables based on function identifiers (FIDs) with inhibit conditions.

The Function Inhibition Manager is closely related to the Diagnostic Event Manager because inhibiting conditions can be based on the status of diagnostic events. The Function Inhibition Caller block calls the FiM service interface FunctionInhibition to initiate the GetFunctionPermission operation.

Enter the name of the client port the AUTOSAR software component uses to call the FiM service interface FunctionInhibition.

Programmatic Use

Block Parameter: PortName
Type: character vector
Values: 'FunctionInhibition'
Default: 'FunctionInhibition'

This block supports the FiM operation GetFunctionPermission and generates inports and outports for this operation. This operation queries the Function Inhibition Manager to check if it has permission to run associated functionality. Permissions are based on the inhibition configuration created by using the Diagnostic Service Component block. The operation returns true if the functionality has permission or false if the functionality is inhibited.

The Operation parameter must be set to an operation supported by the schema currently specified by the model. The list of operations on the block parameters dialog reflects the operations supported by the current schema.

Programmatic Use

Block Parameter: Operation
Type: character vector
Values: 'GetFunctionPermission'
Default: 'GetFunctionPermission'

Block sample time. The default sets the block to inherit its sample time from the model.

Programmatic Use

Block Parameter: st
Type: character vector
Values: -1 | scalar
Default: -1
