Device Transition

Manages data transfer between components that operate on different HIL device.

Manages data transfer between components that operate on different HIL device in a multi device setup. Input and output execution rates may differ.
  • Maximum vector width is 16.
  • Maximum number of devices transition components from device A to device B depends on a chosen device type.

In order for two Signal Processing circuits that run on different devices to exchange data, they should be connected using the Device Transition component as illustrated in Figure 2.

Figure 2. Example application of Device Transition

Device Transition component can introduce a delay of one execution rate.


  • Input (in)
    • Input signal coming from the source device.
      • Supported types: uint, int and real.
      • Vector support: yes.
  • Output (out)
    • The output signal present on the destination device, with the same value as the input signal. The execution rate of the signal is defined using the Execution rate property.
      • Supported types: uint, int, and real.
        • The output type is inherited from the input signal.
      • Vector support: yes.
        • The vector length is inherited from the input signal.


  • Initial value
    • Type in the initial value of the output signal at the beginning of the simulation.
  • Execution rate
    • Type in the desired signal processing execution rate. This value must be compatible with other signal processing components of the same circuit: the value must be a multiple of the fastest execution rate in the circuit. There can be up to four different execution rates, but they must all be multiple of the basic simulation timestep. To specify the execution rate, you can use either decimal (e.g. 0.001) or exponential values (e.g. 1e-3) in seconds. Alternatively, you can type in ‘inherit’ in which case the component will be assigned execution rate based on the execution rate of the components it is receiving input from.
