• JTAG Configuration Chain

The FPGA on the VCC board can be configured via a JTAG chain. The image below shows the devices on the chain, the Virtex FPGA and a Xilinx CPLD.

It is possible, and probably easier, to use impact from the command line. By using batch files, you can store a set of impact commands. These batch files are then run by using impact's -batch flag, as shown below. The batch file in this case being called boardID.batch.

> impact -batch boardID.batch

The batch file shown below will display the contents of the board's JTAG chain and is useful for checking that the cable is all connected up OK.

# Impact batch File
# Board ID commands for VCC VW-300 board

setMode -bs                          # Set to Boundary Scan Mode
setCable -port lpt2                  # Use Parallel port

identify                             # Identify devices
info                                 # Display information on devices

quit                                 # Quit Impact

This second batch file can be used to configure the FPGA. It reads a bit file called bitFile.bit. You will also need the bsd file xc9536.bsd for the CPLD. This can be found within the files installed with ISE.

# Impact batch File
# Program commands for VCC VW-300 board
# Program Virtex and bypass CPLD

setMode -bs                          # Set to Boundary Scan Mode
setCable -port lpt2                  # Use Parallel port

addDevice -p 1 -file "bitFile.bit"   # Bit File for Vitrex
addDevice -p 2 -part "xc9536.bsd"    # BSD file for CPLD

program -p 1                         # Program device 1 - FPGA

quit                                 # Quit Impact
