Hi kurapix,
we developed a plugin for embedded targets like MSP430, PowerPC, TriCore. This plugin will be released in the next two weeks. This plugin checks the compilerID and modifies the Debug menu. So the user can start tools like simulator, jtag server, external debugger (e.g. insight) for a corresponding project. The plugin will start the debugger with the arguments $(TARGET_OUTPUT_FILE) so the user can simultonously debug different projects. If you like I can attach the sources a soon we release the code, perhaps this could solve your problem.
Regards,
Mario
