Honored ContributorI used the Quartus II software which has SOPC builder in it. However, I am not sure what changes they have made to the software since then so not sure what options are available. If you go here:
http://www.altera.com/products/software/sfw-index.jsp you can download the software off the Altera site. Although again I am not sure if the free web edition will give you access to the SOPC builder. The link below this has a lot of information on SOPC builder http://www.altera.com/support/software/system/sopc/sof-sopc_builder.html The error seems like you don't have the correct type of cable configured in your software (my inital guess without looking at it). There are multiple types of cables to use for the jtag including RS232 and USB. Some troubleshooting techniques: 1. Check cable connection is correct on both ends and you don't have them flipped or inverted. 2. Check to make sure your PC is recognizing the cable 3. Make sure your software is communicating with your cable. 4. Ensure your software is configured correctly. Hope this helps you. I would suggest getting familiar with the Altera support section. They do a pretty good job of explaining a lot of their products and how to configure things.
