  1. 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!
  2. Hi, I have a ZEDBOARD which I want to interface it to an analog input signal and see the sinusoidal output. i'm following lab 3 tutorial by Adam Taylor. So, as for the first step, I tried to connect the signal generator to Vn and Vp. I expected to see the sinusoidal shape of the voltage in XADC dashboard (XADC wizard demo). and also set the ENABLE_ALL_AUXILIARY_CHANNELS check mark, which will include Vp/Vn. I set the function generator to frq 50Hz and amplitude 400-600 vpp, or DC also I applied and checked the signal on the dashboard and serial oscilloscope both. But, the board produces no reaction and the Vp_Vn channel still gives an uneven sine wave or i guess its noise or something else. I tried so many times but still i'm stuck at this point . Could anyone suggest any solution or PoW ?

    Board for OpenCL

    Hi I want to work with OpenCL but I don't know what board is recommended for that. Someone could tell me what is the best digilent board for OpenCL, please? Thanks in advance.
  4. Hello,I kindly ask you to send me information about FPGA boards with the ability to measure the power consumed by the IP.kindly note that the aim of this question is to have a board that supports the power consumption measurements on the FPGA itself .So please inform me if is it available such kinds of fpga boards with this features to evaluate the power consumption.Merci!Yehya NASSER,
