VHDL is a HDL ( Hardware Description Language) currently used for the design of digital systems, especially complex ones. #Fpga projects altera cyclone ii code#Clicking on the button "Assignment summary", we can examine, as a table, all the assigned associations, both from the point of view of the schematic and from the point of view of the FPGA board:īy clicking on "Generate Project", the Deeds-DcS will generate all the VHDL code and the project files necessary for the Quartus® II software, Intel/FPGA (ex Altera Corporation). B0 the eight red LEDs' LEDR.LEDR have been assigned to the outputs R7.R0 finally, the eight green LED's LEDV.LEDV are connected to the outputs G7.G0. For the convenience of the experimenter, the associations are highlighted also in the next figure, that can be considered as a "control panel", useful for testing the physical system:Įight of the available switches, Sw.Sw ( nomenclature of the manufacturer), have been associated to the inputs B7. As a reference, it is possible to download, as PDF, the DE2 board user manual.Īll the needed associations between Deeds-DcS schematic and the FPGA board input/outputs are already set in the given schematic: it is not necessary to modify them. In this window the user chooses firstly the FPGA board that intends to use (up left) then associates to each input and output of the Deeds-DcS schematic (highlighted in red on the bottom left of the window) one of the resources available on the board (highlighted in red on the bottom right of the window). The command "Test on FPGA" opens the dialog window shown below: The Deeds-DcS offers the command "Test on FPGA" (as highlighted in the following figure, available both in the "File" menu and in the command bar): We recommend to use the schematic supplied, without modifying the input and output terminations, since they contain the information needed for exporting the project on the FPGA board.Īt this point we begin the procedure for the physical implementation of the project in the DE2 FPGA board. A test sequence is available in the Timing Diagram window, where a 16 numbers sequence is defined (from 0 to 15 dec.). It is useful to verify the network behaviour in the Deeds-DcS, using both the animation and timing simulation. The 8-LEDs' output component, useless during the simulation, had been added for testing purpose on the FPGA board. The combinational network, made up of 7 EXOR gates, generates the output G7, G6, G5, G4, G3, G2, G1 and G0. The 8-bits code input is represented by the B7, B6, B5, B4, B3, B2, B1 and B0 lines. The example circuit is a simple 8-bits code converter, from natural binary to Gray code (click on the following figure to open the schematic in the Deeds-DcS): We imagine that this circuit will be the result of our project activities, and that all the assigment specifications had been functionally verified, using interactive (and/or timing) simulation. To focus on the method of the prototype implementation, let we use, as working example, a very simple circuit. DE2 may host simple introductory projects, like the one we are presenting here, and sophisticated ones that may include one or more microcomputers. The core of DE2 is an FPGA ("Field Programmable Gate Array"), Intel/Altera Cyclone® II 2C35, composed by more than 30.000 Logic Elements (LE). It includes several I/O devices and interfaces, from simple ones (switches, pushbuttons, LEDs, seven segment displays) to complex devices (LCD matrix display, Ethernet network interface, USB 2.0, SD memory cards, analog audio I/O, analog video input, VGA video output and other). Terasic/Altera DE2 board is conceived for the practical implementation of digital and mixed-signal circuits, even quite complex ones. The target is to implement a physical prototipe of the project and test its behaviour. In this page we examine the necessary steps to implement a DEEDS project on an Terasic/Altera DE2 FPGA board.
