Quartus 15.1.2. use Design partition with In-System Memory content Editor

Hi Everyone, 

 

Does anyone know if it's possible to generate design partitions (qxp file) that contains memory that I can access via In-System Memory Content Editor at a higher level? 

- I'm using Quartus 15.1.2 

 

More details to explain my issue: 

1. I have a sub module that contains a memory instance (which is created with megawizard with option Enabled for In-System Memory Content Editor") 

For example this memory instance is called "Mnew" 

2. Then I export this module as "submodule.qxp" file. 

3. I import the submodule.qxp file into a different design (a top level)  

4. Then generate an image (top.sof file)  

5. Then loads the image to a device 

6. Then use In-System Memory Content Editor to access this memory instance "Mnew" 

 

I have tried these steps, but the In-System memory content editor only seems to find memory instances at top level :(

I'm pretty sure you can't do this. The .qxp file is meant to be a self-contained file like a design file but doesn't allow connections to it other than those to connect it to the rest of the design.

Hi sstrell. Thanks for confirming this.  

I'm looking for an alternative way (last attempt).  

Please let me know, if you have an idea how I can keep a design partition (.qxp file) and at the same time get the ability to use the standard memory debug features from quartus. 

 

Thinking out loud:  

It seems, the interface connections between the memory instance and USB-blaster has been inferred by the tool. 

Perhaps, there is a way I can add interface ports to my submodule, such that it can be extended at the top-level and get it recognized by the In-System Memory Content Editor?
