Analog In


The Analog In functionality of the OPAL-RT Board driver provides the simulation with the analog input acquisition data obtained from the analog input channels of the OP5340 modules installed in the simulator.

The data values are transferred to the simulation through the DataOUT ports of the FPGA.

The data port numbers and the location of the analog input modules in the simulator are specified in the bitstream configuration file, which must be provided in the General section of the configuration of the OPAL-RT Board driver.

Once the driver has read the bitstream configuration file, the user can see the location of the analog input modules and can configure them.

The OPAL-RT Board driver can control all of the analog input modules of the simulator at the same time. Therefore, the maximum number of analog input channels is limited by the hardware configuration of the simulator in use.


The present document describes the usage of the standard analog in the functionality of the simulator. For the resolver in functionality that makes use of the analog input modules of the simulator, see the Resolver In documentation.

Once the bitstream configuration file has been parsed, the location of the analog input modules becomes visible to the user. The channels of the modules are grouped into bunches of 8. By clicking on each group of 8, the user has access to the configurable options of the group.

Channel Group Configuration

  • Enable

Checking this box enables the acquisition of analog data for the channels in the group once the simulation has started.

Clicking on Enable also adds the group of 8 channels as a connectable vector in the Configuration panel of RT-LAB. This means that if the user wishes to display the analog data received in the model, connections must be made between points in the model (in the form of OpInput blocks) and the analog input connectable points.

Connections with LabView panels are also possible.

To create a connection, the analog input vector of connections has to be drag-and-dropped onto an appropriate OpInput block in the Configuration panel of the RT-LAB project.

A connection can be made either on the entire vector or on each individual item of the vector (i.e. analog input channel).

Signals Configuration

Channels in analog input groups do not have any parameters to configure.

Characteristics and Limitations

For the connector pin assignments, the user should refer to the carrier documentation.

The current version of the analog input functionality of the OPAL-RT Board driver has the following limitations:

  • Limitations will be added as they are found
