Urgency: Standard

General Description:
Xchecker, Parallel, and JTAG Cables what do they do and how do I identify them?


Solution 1:

You can use the Xchecker cable to download to a FPGA, verify
the FPGA's configuration, and probe an FPGA's internal signals.
You can use the Window's based Hardware Debugger software
or the DOS based Xchecker to communicate with the cable.
You can tell you have an Xchecker cable by looking at the
model id on the pod, it should be DLC4.

The Parallel Download cable can be used to download to a FPGA.
You can use the DOS based Xchecker program software to communicate
with the cable.  Although the Hardware Debugger software lists
the Parallel Download cable for download, because of a flaw
in the software the Hardware Debugger software can not be
used to communicate with the parallel download cable.
You can see if you have a parallel cable by seeing if the
id number on the pod is ML5.

The JTAG cable also known as the EZTAG cable is used to
download to a 9500 CPLD.  You can use the Windows based EZTAG software
or the JTAG Programmer that comes with M1 to communicate with the
cable.	 The JTAG Cable can be used to program FPGA's when using
M1.4 Hardware Debugger or later, see (Xilinx Solution 3630).
The model id number on pod of a JTAG cable is DLC5.
