Hi there guys! I want to build a router in order to use it as a generic component to build a mesh interconnections networks of 64 cores. So to begin with I must build the one router. I am planning in using the FIFO for input buffer an FSM to control the read and write a XY logic element for routing the same for the output only there I ll use an arbiter to arbitrate the request and a central crosspoint matrix. Soto begin with I want to build the FIFO having inputs of :data in ,clk, write,read and outsof : the first4bits of the header are used for routing ,data out,fifo full, fifo empty. Thank you in advance.

Open Quartus II Menu 'Tools' -> 'Megawizard Plugin Manager' Select 'Memory Compilier' -> Fifo Enter your parameters. Or Open ISE 'Tools' -> 'Core Generator' 'Memory & Storage Elements' -> Fifo Enter your parameters.
I am getting a message there is now project open!I have opened a new project but again I cannot load the fifo! :( Is it because I have the free version of ISIM?
Ok I have done it...But I dont really know how to set the right parameters before generating it :( I need Data input ,clk,write and read , and outputs :first 4 bits of header for routing , dataout ,fifofull,fifoempty. Can I implement these ports to have the requesting fifo?

I think, you should sit down, take some books and Xilinx documents and read about the basics. Look, what Xilinx offers you in their fifo-design. And then look, what signals you have to combine for your purpose.
I think you are right and thats what I am doing... Any suggestions on books or xilinx documents?
Go to Google, enter "xilinx ise fifo generator" and take what you think fits best your needs. Have a nice weekend... ;-)
Could I please ask how can I testbench a core generator FIFO? I mean I have done all the steps to generate the fifo with the i/o i need and I cannot understand what to do next to tb it! Will I have to write the tb?Is there a tb ready in the core to use? cheers :)

> Will I have to write the tb? Yes, I think so. Normally you have a global system, where the FIFO is only a small part. I do normally a simulation of the global system... > Is there a tb ready in the core to use? I don't think so. FIFO is not MIG. Duke
