An iterator subsystem runs one or more times at the
current time step when enabled by a control block. A control
block implements control logic similar to that expressed by
programming language loop constructs such as
Use a While Iterator Subsystem block to repeat execution of an algorithm as long as a logical condition is true.
Use a For Iterator Subsystem block to repeat execution of an algorithm until an iteration variable exceeds a specified iteration limit.
Use a For Each Subsystem block to apply an algorithm to individual elements or subarrays of input signals or mask parameters.
Each block inside a For Each subsystem that has states maintains a separate set of states for each element or subarray processed by the subsystem. By contrast, blocks inside While Iterator and For Iterator subsystems use the same states throughout successive iterations of the subsystem.
|While Iterator Subsystem||Repeat subsystem execution during simulation time step while logical expression is true|
|For Iterator Subsystem||Repeat subsystem execution during simulation time step for specified number of iterations|
|For Each Subsystem||Apply algorithm to individual elements or subarrays of input signals or mask parameters|
Execute subsystem multiple times during time step in response to control block.
Iterate algorithm over groups of signals, subsystems, and parameters.
Use signal logging in For Each subsystems.
