SignalOut
This block writes a signal to the OML workspace. At each activation step, time, input value and some information on the type of activation are recorded.
Library
Activate/SignalExporters
Description
The SignalOut block is used to put simulation data in the OML workspace. Each sampling time, both time and value of input are recorded.
Data is then exposed in the workspace as a Twin Activate sigs object.
Data can also be read by a SignalIn block that can reconstruct the original signal fed to the SignalOut block.
Consider, for example, the signalOut block with 3 input ports and the signal name "A".
After the simulation, the time instants of data stored in "A" can be retrieved using "A.time" command and the data matrix corresponding to input port "i" is retrieved using "A.ch{i}.data" command in the OML window.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
nin | Number of inputs | Number of inputs. Integer value. | Number | |
varname | Variable name | Name of the OML variable to be set in the OML workspace. | String | |
externalActivation | External activation | Specifies whether the block receives an external activation or inherits its activation through its regular input ports. When External Activation is selected, an additional activation port is added to the block. By default, external activation is not selected. | Number | 0 |
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
subsample | Sub-sampling rate | Sub sampling rate should be greater than 1. | Scalar | |
increasingTime | Strictly-increasing time | If enabled, a strictly-increasing time sequence will be created. | Number | 0 |
buffsize | Buffer size | Size of the buffer (gives the total number of samples recorded during the simulation). This is a circulate buffer. | Scalar | |
R_MP | Register mesh points | Register the continuous time step. Event code is 0. | Number | 0 |
R_DE | Register discrete events | Register the discrete time event. Event code is 1 | Number | 0 |
R_MPLL | Register left limit of discrete events | Register the event just before a discrete event. Event code is -1. | Number | 0 |
R_ZCLL | Register left limit of zero crossings | Register the event just before a zero crossing event. Event code is 4. | Number | 0 |
R_TRY | Register try points | Register the events in try phase. Event code is 2 or 3. | Number | 0 |
