Is it possible to create netlist for module which include one submodule like an RTL source?

If you set l4 as a design partition, you can use the root partition reuse flow documented here:

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-qpp-block-based-design.pdf

You're basically locking down the I/O design and including all the other submodules in the root partition along with the I/O, leaving l4 as a "doughnut hole" in the middle. You then reuse the root partition with all the other submodules and put whatever you want in l4.

I think I was happy too early.

My approach worked when I use first level submodule, but when I put it deeper, I faced problems.

I used to ways

1. Empty partition for Blackbox module was created in main netlist project. Root partition with Empty subpartition for main netlist project was exported. exported partition was imported in another project. Now I faced the error "Error (35013): Found unexpected partition in previously generated netlist with no corresponding partition definition in the current project" within partition merge.

2. I didn't create partition for submodule (instantiated like a black box), I created only root one. The partition was imported to another project successfully. But I added source instead black box, but it not affects to design.

Unfortunately, almost all info about such tasks are for Quartus Pro, but I use Standard edition.

BR, Vlad.

I attached two .qar archive with the Quartus project.

"top heartbeat" is design which supposed to be netlist (with the unencrypted source cnt_l2)

"top" is design which supposed to use "top_heartbeat" like a netlist. Source "cnt_l2" must be changible in top project.

In the example i represented "way 2" from last post. To check "way 1" please execute "set as Design Partition"->Netlist type Empty->Export Design Partition for "top_heartbeat" project. New .qxp include to "top" projct. In such case I catch error.

You can refer to the document below for creating a design partition. This is based on Quartus standard edition.

I checked and don't think it is possible to create netlist for module which include one submodule like an RTL source, as the qxp is in the top already. you cannot have a submodule with a source in it.
