Synthesize the Design
11. Right click on Generate Programming file and select Run
51
Synthesize the Design12. Finally, an FPGA configuration data (*.bit) file is generated.
52
Download and Verify The Design
This is the last step in the design verification process. This section provides instructions for downloading the MUX design onto the Spartan 3 PCB.
1) Connect the 5V DC power cable to the power input on the demo board (J4). (note: you may see a sequence of numbers begin to flash on the 7-segment LEDs, this is just a test configuration stored in the flash memory on the PCB and you can manipulate the various switches and button, except for the PROG button, on the PCB to see the operation of the LEDs and 7-segment displays).
2) Connect the download cable between the PC parallel port and the demo board (J7). 3) Select Synthesis/Implementation from the drop-down list in the Sources window and select Mux_Schematic or Mux_vhdl (or whatever you named you design) in the Sources Window. In the Processes window, expand the Generate Programming File process and double-click the Configure Device (iMPACT) process.
53
Download and Verify The Design1. Processes window, expand the Generate Programming File
process and double-click the Configure Device (iMPACT) process.
54
Download and Verify The Design2. iMPACT opens and the Configure Devices dialog box is displayed. In the
Welcome dialog box, select Configure devices using Boundary-Scan (JTAG). Verify that Automatically connect to a cable and identify Boundary-Scan chain is selected. Click Finish.
55
Download and Verify The Design3. When programming is complete, the Program
Succeeded message is displayed.
56
Download and Verify The Design
4. Close iMPACT without saving. Your design is downloaded into the FPGA and you can begin to verify the design by manipulating swithes/buttons and observing LEDs as specified in your design.
