NVRAM Service Component

Configure AUTOSAR NVRAM Services and Runtime Environment (RTE) for emulation

• 

Libraries:
AUTOSAR Blockset / Classic Platform / Basic Software / NVRAM Manager (NvM)

Description

The NVRAM Service Component block provides reference implementations of NVRAM Manager (NvM) services supported by AUTOSAR Basic Software (BSW) caller blocks. When coupled with NvM caller blocks, the reference implementations enable you to configure and run system-level or composition-level simulations of AUTOSAR NvM service calls.

The block has prepopulated parameters, including RTE block ID parameters and NvM NVRAM Properties parameters. Examine the parameter settings and consider if modifications are required based on how you are using the NvM service operations.

Examples

Parameters

Block ID — ID that identifies service block

1 (default) | scalar

The RTE tab table lists component client ports and their mapping to NvM service block IDs. Each row in the table represents a call into NvM services from a Basic Software caller block. Calls that act on the same NvM block use the same block ID. Check the block ID mappings. For examples of mapping NvM client ports to block IDs, see Simulate AUTOSAR Basic Software Services and Run-Time Environment.

Maximum number of memory blocks — Maximum number of memory blocks to use in NvM service operations

10 (default) | scalar

Specify maximum number of memory blocks to use in NvM service operations.

Initial Value — Initial values of NvM client ports

0 (default) | real, finite scalar or vector

Specify the initial values of the NvM client ports as finite, real-valued scalars or vectors. The values must be scalar, or have the same dimensions as the input signal.

R2022b: Initial values for NVRAM Service Component blocks

R2022b enables you to define initial values for NVRAM services that are accessed during simulation by basic software. To configure the initial values, you can open the NVRAM Service Component block parameters, click the Initial Values tab, and set an initial value for each NvM client port.
