Hi there,
I am following an application note (APNOTE 768) from Aldec to simulate Nios II in Active-HDL using a standard design example from Altera. The apnote was written for the legacy tools Nios II 9.1 IDE, not for the new tools Nios II 9.1 Software Build Tools for Eclipse. So I wasn't surprised the tutorial in the apnote did not work when I switched to the new tool. But did anyone have any success making it work? I noted all the configurations mentioned in the tutorial regarding the Nios II 9.1 IDE and found the relevant configurations in the Eclipse, but that didn't seem to cut it. Here is the link to the apnote: http://support.aldec.com/knowledgebase/article.aspx?aid=000768 Thanks, HuaLink Copied

For IDE tools, when I set it as "ModelSim only, no hardware support", it will generate lots of DAT and SYM files, which initializes the memory in simulation tools.
But for Eclipse, it generates ELF and MAP files instead. Does ModelSim support to read those files as input for simulation? Thanks, Hua- Mark as New

I wonder which script generate the following response:
