Stop Simulation

Stop simulation when input is nonzero

• 

Stop Simulation 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 / Sinks
HDL Coder / Sinks

Description

The Stop Simulation block stops the simulation when the input is nonzero. The simulation completes the current time step before terminating. If the block input is a vector, any nonzero vector element causes the simulation to stop.

When you use the Stop Simulation block in a For Iterator subsystem, the stop action occurs after execution of all iterations in the subsystem during a time step. The stop action does not interrupt execution until the start of the next time step.

You cannot use the Stop Simulation block to pause the simulation. To create a block that pauses the simulation, see Pause Simulation Using Assertion Blocks.

Examples

Stop Simulation Block with Relational Operator Block

This example shows how to control when a simulation stops by using a Stop Simulation block with a Relational Operator block. When you simulate the model, the model stops simulation when the simulation time reaches 10.

Extended Examples

Model an Anti-Lock Braking System

Model a simple Anti-Lock Braking System (ABS). The model simulates the dynamic behavior of a vehicle under hard braking conditions. The model represents a single wheel, which may be replicated a number of times to create a model for a multi-wheel vehicle.

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using Simulink® Coder™.

Not recommended for production code. Relates to resource limits and restrictions on speed and memory often found in embedded systems. Generated code can contain dynamic allocation and freeing of memory, recursion, additional memory overhead, and widely varying execution times. While the code is functionally valid and acceptable in resource-rich environments, smaller embedded targets often cannot support such code. Usually, blocks evolve toward being suitable for production code. Thus, blocks suitable for production code remain suitable.

Generated code stops executing when the stop condition is true.

HDL Code Generation

Generate VHDL, Verilog and SystemVerilog code for FPGA and ASIC designs using HDL Coder™.

HDL Block Properties

PreserveUpstreamLogic

Control the removal of unconnected logic. The default is off, which means unconnected logic is not preserved in HDL code. For more details, see PreserveUpstreamLogic (HDL Coder).

PLC Code Generation
Generate Structured Text code using Simulink® PLC Coder™.
