NVRAM Manager (NvM)
Description
The AUTOSAR standard defines a NVRAM Manager (NvM) service as a part of Basic
Software (BSW) that runs in the AUTOSAR Runtime Environment (RTE). AUTOSAR
software components access NvM services through client-server calls. The
NvMServiceCaller block calls the AUTOSAR NvM service interface
NvMService
by to initiate specified
operation.
Examples
Simulate AUTOSAR Basic Software Services and Run-Time Environment
Simulate AUTOSAR component calls to Basic Software memory and diagnostic services by using reference implementations.
Parameters
Client port name — Name of client port AUTOSAR component uses to call NvM
service interface NvMService
NvMService
(default) | character vector
Enter the name of the client port the AUTOSAR software
component uses to call the NvM service interface
NvMService
.
Programmatic Use
Block
Parameter:
PortName |
Type: character vector |
Values:
'NvMService' | unique
name |
Default:
'NvMService' |
Operation — Specify operation defined in NvM service interface NvMService
GetDataIndex
(default) | GetErrorStatus
| EraseNvBlock
| InvalidateNvBlock
| ReadBlock
| RestoreBlockDefaults
| SetDataIndex
| SetRamBlockStatus
| WriteBlock
Select the operation that the AUTOSAR software
component calls from the NvM service interface
NvMService
. The AUTOSAR
standard defines the operations. After you select
the operation, the inports and outports for the
block are generated to support the operation.
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:
'GetDataIndex' | 'GetErrorStatus' |
'EraseNvBlock' | 'InvalidateNvBlock' | 'ReadBlock'
| 'RestoreBlockDefaults' | 'SetDataIndex' |
'SetRamBlockStatus' |
'WriteBlock' |
Default:
'GetDataIndex' |
Argument specification — Specify data type and dimensions for operation read or write access
uint8(1)
(default) | character vector
A MATLAB expression that specifies data type and dimensions for data to be read or written by the operation.
To specify a multidimensional data type, you can use array syntax, such as
int8([1 1; 1 1])
.To specify a structured data type, you can create a
Simulink.Parameter
data object, type it with aSimulink.Bus
object, and reference the parameter name.
For examples, see Argument Specification for Simulink Function Blocks.
Dependencies
Specify this parameter when
Operation is set to
ReadBlock
,
RestoreBlockDefaults
, or
WriteBlock
.

Parameter:
ArgumentSpecification |
Type: character vector |
Values:
'uint8(1)' | character
vector |
Default:
'uint8(1)' |
Sample time — Block sample time
-1 (default) | scalar
Block sample time. The default sets the block to inherit its sample time from the model.
Programmatic Use
Block
Parameter:
st |
Type: scalar |
Values:
'-1' | scalar |
Default:
'-1' |

Version History
Introduced in R2016bR2023a: Basic Software caller blocks support all AUTOSAR schema versions
Starting in 23a, Basic Software caller (BSW) blocks support all AUTOSAR schema versions supported by AUTOSAR Blockset. The BSW blocks inherit the same schema version specified by the model. Code and ARXML generated from the component reflect the schema version specified on the model. When you change the schema version specified by the model, the software automatically replaces software calls to the correct operation.
In some cases, the software may prompt you to confirm a change when moving between schema versions. The software may also display a warning as you update to new schema versions as some modeling patterns are no longer compliant with the configured AUTOSAR schema version.
