SLRT Overload Options

Select CPU overload options

SLRT Overload Options block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Real-Time / Target Management

Description

The SLRT Overload Options block configures CPU overload options for the model rate identified through the TID port. This block outputs the current CPU overload count for the identified rate. If the Enable TET Output parameter is on, the block outputs TET data that you can mark for data logging in the Simulation Data Inspector.

Examples

Monitor and Tune Maximum Number of CPU Overloads

Design a model that uses the SLRT Overload Options block to monitor the rate at which CPU overloads occur.

Ports

Input

TID — Task ID

int

Connect any signal from the model to the TID (Task ID) port and the block applies the overload options to the model task in which the signal executes.

Example: 1

Output

Count — Overload count

int

The CPU overload count for the selected model rate.

TET — Task Execution Time data

overload data

When enabled by the Enable TET Output parameter, the CPU overload data is output for display in the TET monitor and the Simulation Data Inspector.

Parameters

Startup Duration — Select startup steps for ignoring CPU overloads

1 (default) | int

The number of startup execution steps for which overloads are ignored.

Programmatic Use

startupDur

Source — Selects CPU overload input during startup

Tunable Parameter (default) | Input Port

The source of CPU overloads for the model rate during startup can be a tunable parameter or a block input port.

Programmatic Use

startupDurSrc

Max Overloads — Select maximum CPU overloads

0 (default) | int

The number of accepted overloads before execution is halted. There is a separate overload counter for each sub-rate. Each counter is compared to Max Overloads separately, not compared to the sum of the counters.

Programmatic Use

maxOverload

Source — Selects CPU overload input after startup

Tunable Parameter (default) | Input Port

The source of CPU overloads for the model rate after startup can come from a tunable parameter or from the block input port.

Programmatic Use

maxOverloadSrc

Enable TET Output — Enable output TET data

off (default) | on

When enabled, the CPU overload data is output for display in the TET monitor and the Simulation Data Inspector.

Programmatic Use

TETFlag

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
