Hi all, my project currently will use multiple memory block with some initial data. If I try to use on chip memory such as on port ram, and I generate the memory block through the wizard. I known I need to create a mif file for each memory. But how can I link each mif file to the corresponding memory. By creating new on chip memory for each mif file? or I can write the new architecture in the memory file i get from wizard?Thanks.
When you generate the ram from the wizard, you can specify the .mif file to use for initialisation.You only need a .mif file if you need the ram to be filled when the power is turned on. .mif file is not required if you intend to fill the ram yourself during run time.
Thanks for the help.If I need 100 memories with same kind of memory block but with different mif files, how can I do that? I will have 100 mif files: m1_data.mif to m100_data.mif But I want to link these files to the mem.vhd which I got from wizard, so I need to generate 100 .vhd files for each .mif file, is that right? Or there is another way to do it?
Yes. You can instantiate the rams yourself, and you could instantiate them inside a generate loop and generate the .mif string for each ramor you can infer the ram and use attributes to specify the .mif file to use, but that wont work in simulation. But you can use a function to initialise the ram yourself.
