Honored ContributorHi jcn,
That is very odd to have support tell you update your Java version (It may be a new support engineer who got your service request, but I don't know the details of how you described the problem and requested the patch). The suport engineer usually tries to analyze and replicate the problem by trying to build a test case or if you can provide a design example that shows the problem it can speed up the debug process and then they can quickly find out if there is a workaround, software fix or file a bug report on the problem. This should be the process to request a patch: I would file a Service Request at the Altera mysupport (http://www.altera.com/mysupport): http://www.altera.com/mysupport In the Service Request describe that you are having problems with the tri-state bridge component giving a java error in SOPC Builder version 7.1 (or 7.1sp1). You should ask for one of the following patches for Quartus II: Quartus II 7.1 - patch 0.20 Quartus II 7.1sp1 - patch 1.04 The support person should be able look up the patch and determine if is applies to your specific issue. Ideally they would be able to run a test case on your design to make sure it works so that you are not wasting your time installing a patch that may not solve your issue. Usually if you provide enough information i.e. an example design, copy of error text and perhaps a screenshot of the error is usually enough to determine if the problems can be fixed by the patch. If the support person who analyzes your problem does not know about software patches. I would request to escalate the issue to a more experienced support person to review the Service Request. Post back here if the patch fixes your problem. Regards, -ATJ Here is the readme file from one of the patches (err, I hope there is no copyright issues posting this :D ): //**************************************************************** readme_patch_7.1_1.04.txt Readme file for Quartus II 7.1 Patch 1.04 Copyright (C) Altera Corporation 2007 All right reserved. Patch created on July 11 2007 Patch SPR#: 246494 SPRs fixed: 243129, 244405 //**************************************************************** Problem: TCL based components which contain a tristate slave produce a NullPointerException when connected to the Tri State Bridge. When opening the editor for the Tri State Bridge, the exception is thrown and the user is unable to parameterize the bridge. Solution: Provide the infrastructure needed by the Tri State Bridge in order to assign the component signals that the bridge will share. Caution - You must either have previously installed the Quartus II software version 7.1 SP1 or must install the Quartus II software version 7.1 SP1 before installing this patch. Otherwise, the patch will not be installed correctly and the Quartus II software will not run properly.
