ChipScope Pro Analyzer - Programming Cable connection fails and "INFO: Cable connection failed." appears in the console


When I attempt to connect to my programming cable, the following message appears in the console:

"INFO: Cable connection failed."

The $HOME/.chipscope/cs_analyzer.log/C:/Documents and Settings/<username>/.chipscope/cs_analyzer.log includes the following error:

"ERROR:Client communication thread failed: java.io.IOException: An existing connection was forcibly closed by the remote host"

I can connect to my cable using iMPACT. How do I work around this issue?


ChipScope Pro analyzer uses the TCP/IP protocol to connect to the cable. This error occurs because the socket specified in the "Server Host Settings" is being used by another application.

To work around this issue, change the socket setting as follows.

1. Open ChipScope Analyzer.

2. Select JTAG Chain -> Server Host Settings.

3. Increment the default setting (e.g., localhost:50001 -> localhost:50002).

4. Repeat step 3 until you can connect to the cable.
