Replace Old Blocks

The primary goal in migration is to replace legacy SimEvents^® behavior with new SimEvents behavior.

This table lists:

New SimEvents blocks to replace legacy SimEvents blocks
Actions to take when there is no equivalent new SimEvents block to replace the legacy block. Some of these actions are also part of the migration workflow.

Old Block	Action for New SimEvents Model
Attribute Function	Wait until Replace Attribute Function Blocks with Event Actions.
Attribute Scope	Wait until If Using Get Attribute Blocks to Observe Output.
Cancel Timeout	Consider not yet migrating your model.
Conn	Simulink^® Inport or Outport block.
Discrete Event Signal to Workspace	Wait until Observe Output.
Enabled Gate	Replace with Entity Gate.
Entity Combiner	Replace with Composite Entity Creator.
Entity Departure Counter	Wait until Write Event Actions for Legacy Models.
Entity Departure Function-Call Generator	Wait until Write Event Actions for Legacy Models.
Entity Sink	Replace with Entity Terminator.
Entity Splitter	Replace with Composite Entity Splitter.
Entity Departure Function-Call Generator	Wait until Write Event Actions for Legacy Models.
Event Filter	Delete (block no longer needed).
Event to Timed Function-Call	Delete (block no longer needed).
Event to Timed Signal	Delete (block no longer needed).
Event-Based Entity Generator	Replace with Entity Generator.
Event-Based Random Number	Wait until Replace Random Number Distributions in Event Actions.
Event-Based Sequence	Wait until Write Event Actions for Legacy Models.
FIFO Queue	Replace with Entity Queue.
Get Attribute	Wait until Connect Signal Ports.
Infinite Server	Replace with Entity Server.
Initial Value	Delete (block no longer needed).
Input Switch	Replace with Entity Input Switch.
Instantaneous Entity Counting Scope	Wait until If Using Get Attribute Blocks to Observe Output.
Instantaneous Event Counting Scope	Delete (block no longer needed).
LIFO Queue	Replace with Entity Queue.
N-Server	Replace with Entity Server.
Output Switch	Replace with Entity Output Switch.
Path Combiner	Input Switch (with All selected).
Priority Queue	Replace with Entity Queue.
Read Timer	For an example, see Measure Point-to-Point Delays.
Release Gate	Replace with Entity Gate.
Replicate	Replace with Entity Replicator.
Resource Acquire	Replace with Resource Acquire.
Resource Pool	Replace with Resource Pool.
Resource Release	Replace with Resource Releaser.
Schedule Timeout	Consider not yet migrating your model.
Set Attribute	Wait until Replace Set Attribute Blocks with Event Actions.
Signal Latch	Delete (block no longer needed).
Signal Scope	Replace with Simulink Scope.
Signal-Based Function-Call Event Generator	Wait until If Connected to Reactive Ports.
Signal-Based Function-Call Generator	Wait until If Connected to Reactive Ports.
Single Server	Replace with Entity Server.
Start Timer	For an example, see Measure Point-to-Point Delays.
Time-Based Entity Generator	Replace with Entity Generator.
Time-Based function-Call Generator	Replace with Entity Generator.
Timed to Event Function-Call	Delete (block no longer needed).
Timed to Event Signal	Delete (block no longer needed).
X-Y Attribute Scope	See If Connected to Computation Blocks.
