  1. Yes, you are right, I did not pay attention to the number of GPIO. I've talked to some people about this, and I think that we can do the communication between the FPGA and Matlab/Simulink without a problem. Can you be a little more specific about this? I have no idea and that is exactly what we don't want to do. It is more like a worst case, I don't think we are getting there. Maybe we can handle the project with only 2 ADC. Do you mind to explain me what is the issue with Matlab? There is one more thing that I haven't talked about, which is the model we are going to implement in Simulink. The signals going to the MOSFET's gate are coming from this model and the ADC data will be used in the Simulink's model in a closed loop regulation. Anyway, the number of GPIOs has already discarded this board. And thanks for your answer!
  2. I'm a newbie here and I’m working on a inverter test bench project where I have two three-phase inverters connected through an inductive load. The idea is to emulate in real time the behave of an electrical machine. To be clearer, the first inverter is going to be tested (Device Under Test) and the second one plus the inductive load must behave like an electrical machine. To do so, we are going to use a FPGA board, which must have the following specifications: - Capable to drive both inverters switching at 50kHz (each inverter has 6 MOSFETs switching at this frequency) - 20 digital I/O - 4 ADC with 16 bits (ideally) and 20MHz at least. The ADCs can be integrated or not in the FPGA board - Capable to communicate in real time with Matlab/Simulink - The board will be placed inside the test bench, in a temperature around 50°C We know that we are going to use Vivado to the VHDL coding, but we are not sure about the ADCs, regarding the Eclypse Z7 with the two Zmod ADCs. We want to code the least possible in VHDL (no VHDL coding if possible), so my questions are: 1) Are we going to have to code the ADC data acquisition? 2) Is the VHDL code generation done automatically by Matlab? I do have the toolbox for HDL coding. Our budget is around €1000,00. I would like to know if the board Eclypse Z7 with the two Zmod ADCs is a good choice for the application and if you have another advices it would be highly appreciated. I hope I made myself clear. Thank you!
