hi, thanks for the tutorial. would you mind please help me to resolve some errors in ModelSim, I synthesis your code "neural networks on fpga" in vivado and then I simulate it with modelsim. I want to read from a file that has 200file txt I want to read it sequentially.you used readmemb(filename , in mem) command but when I run it shows this error "failed to open readmem file in read mode".I just add the whole text files to directory of modelsim but it shows the same error.when I use just one text file like readmemb("test_data_0000.txt" ,in mem ) it doesnt show any error.would you help me to resolve it?
