Chapter 4:
Using the ChipScope Pro Analyzer
Note:
The maximum TCK speed for the cable is often limited by the speed at which the board under
test is able to run. This might be far less than the maximum speed of the cable itself.
Using Multiple Platform Cable USB Connections
To use the ChipScope Pro Analyzer tool with multiple cables, you need three things:
•
Multiple Xilinx JTAG cables connected to one machine
•
Multiple instances of the cs_server application running on one machine, each one
listening to a different port
•
Multiple instances of ChipScope Pro Analyzer tool running on that same machine, or
a different machine (via the remote server feature)
Connecting Multiple Xilinx JTAG Cables to One Machine
To interact with multiple JTAG cables connected to the same machine, you must first be
able to connect multiple Platform Cable USB, Parallel Cable III, or Parallel Cable IV cables
to the machine. For Platform Cable USB cables, you might need to use one or more USB
hubs depending on how many cables you need. For PC3/PC4, you may need one or more
parallel port extender cards.
Note:
Currently, enumerations are not associated with a particular physical Platform Cable USB
cable. This means that rebooting your machine might result in different associations between
enumerations and physical cables. One work-around is to unplug all cables and re-plug them in the
order you wish for them to be enumerated.
Setting Up ChipScope Pro Analyzer tool to Use Multiple Instances of
cs_server
Set up the ChipScope Pro Analyzer tool to use multiple cables first by starting multiple
instances of the
cs_server.ex
e Windows application or
cs_server.sh
Linux
application on the same machine using different ports. For example, to start up two servers
on different ports on Linux, use:
# cs_server.sh -port 50001
# cs_server.sh -port 50002
Starting and Configuring Multiple Instances of ChipScope Pro Analyzer
Start and configure multiple ChipScope Pro Analyzer client instances (see
). Each
instance of the ChipScope Pro Analyzer tool connects to a different cs_server and cable
enumeration.
Opening a JTAG Chain Plug-in Connection
The ChipScope Pro Analyzer tool supports select JTAG chain plug-in connections that can
be opened using the
JTAG Chain > Open Plugin
menu option. Each JTAG chain plug-in
has specific parameters that can be entered into the Plug-in Parameters field of the Open
