How to simulate the FPGA neural network in Altera

If u are creating a new project,i believe that u already has at least a device family installed in the Quartus because u'll need to choose from the listed part numbers for the design u are creating for.

If u start from a new file instead of new project, then the uninstalled device warning make more sense to me..in order for u to create a design project,compile it and open it again in future the Quartus needs to be installed with the devices.

Of course the free web edition has limited feature compared to the subsciption edition.u need to check the altera software download webpage to figure out whether web edition really offers what u are trying to do.
