Automatically handle rate transition for data transfer
Description
Specify whether Simulink® software automatically inserts hidden Rate Transition blocks between blocks that have different sample rates to ensure: the integrity of data transfers between tasks; and optional determinism of data transfers for periodic tasks.
Category: Solver
Settings
Default: Off
OnInserts hidden Rate Transition blocks between blocks when rate transitions are detected. Handles rate transitions for asynchronous and periodic tasks. Simulink software adds the hidden blocks configured to ensure data integrity for data transfers. Selecting this option also enables the parameter Deterministic data transfer, which allows you to control the level of data transfer determinism for periodic tasks.
OffDoes not insert hidden Rate Transition blocks when rate transitions are detected. If Simulink software detects invalid transitions, you must adjust the model such that the sample rates for the blocks in question match or manually add a Rate Transition block.
See Rate Transition Block Options (Simulink Coder) for further details.
Tips
Selecting this parameter allows you to handle rate transition issues automatically. This saves you from having to manually insert Rate Transition blocks to avoid invalid rate transitions, including invalid asynchronous-to-periodic and asynchronous-to-asynchronous rate transitions, in multirate models.
For asynchronous tasks, Simulink software configures the inserted blocks to ensure data integrity but not determinism during data transfers.
