You need to provide more information before your question can be answered (if it can be answered): * Chip manufacturer (Xilinx? Altera? Other?) - typically a logo on the chip. * Chip part number (typically the first row of letters and numbers on the chip - typically the second row is the date of manufacture in the form YYww where ww is the week of manufacture - all numbers are useful) Is there a 10 pin or 14 pin header near the chip? If so, check for power and ground on the appropriate pins for a standard JTAG pinout. https://www.google.com/search?q=jtag+connector+pinout https://www.google.com/search?q=jtag+connector+pinout If the card has a clearly identifiable JTAG connector and is a common FPGA, you should be able to look up the chip part number on the manufacturer's web site and find the software tools that support that chip. You will need to figure out which JTAG interface the tool set supports - if it is a newer toolset, it probably supports a relatively inexpensive USB-attached JTAG. If it is an older toolset, it may need a specific, often expensive and likely no longer available JTAG interface.
