fpga hardware in the loop simulation

[tommpogg]

Hi,

I would like to know if it possible to perform an hardware in the loop simulation with a FPGA.

Basically, I have got a dynamical system modeled with the "control design and simulation" toolkit on a host PC and a controller designed and implemented on a NI FPGA (NI PXIe-5641).

Is there a way to execute the controller on the FPGA and the simulated system on a host PC?

Thank you

Hello tommpogg,

You have to options depending on the hardware you want to use:

 If you want to execute the FPGA code in hardware, just implement the communication with your device, considering the Control Design Loop as a regular While Loop.

However, a better option is to execute the FPGA code without hardware, saving all time you need to spend compiling code. This link has information about that option:

After reading this information, do you have any other doubt or question?

Thank you for the reply.

I have one more doubt about sampling time: the FPGA samples the input signals at 40MSamples/s, will the Host be able to communicate with the FPGA (retrive and send data) and process the simulation loop at such a speed?
