Calculating the number of gates I need..??

I wonder how I can calculate the number of gates I will need for an application. For example, if I need a 16Bit-Counter, how much gates will this need? Which device will fit this application?

If you have to do FPGA design and board design in parallel then you have to estimate the ressource usage. This should be done by experienced FPGA designers. There is a possibility to do that board layout for two different devices and decide later which one to use. Altera calls this migration device. But to be honest, I never had to use this.

Do you use IP cores? A DRAM controller? A NIOS? In that case you can find information about the ressource usage of these modules. For the rest you will have to estimate.
