Hi, I am very confused and need some help.
There is an error when I creat a porject with exapple design xapp739. The error is as follow:
ERROR:HDLCompiler:1654 - "E:\AXI_PROJECT\new_xapp739\projnav\ipcore_dir\vdma_synth.v" Line 252: Instantiating <inst> from unknown module <axi_vdma>
My ISE version is 13.4, The axi_vdma ipcore version is 5.00.a.
I have creat an instantion about axi_vdma using CORE Generator, Why have the mistake?

Please stop cross-posting this same thread to many forums. One post is enough. Take the time to make sure it ends up in the correct place, and the right people will help you answer it.
Have you tried cleaning the project and re-generating the core?
Is this a verilog design or VHDL? I seem to recall a known issue with one of the combinations of core version/ISE version where a verilog instantiation of the VDMA resulted in incorrect .prj being generated. In which case, you can black box the core and bring it into your project as an NGC or use a newer version of the core and/or software.

Of cause, I have regenerate all ipcores. Also I have trid manys ISE version, ISE13.2, 13.4, 14.1, 14.2.
But only in ISE 14.2, there is no this mistake.

Additionally, the IPcore AXI_datamover has the same problem.
Now, even if i instiantiate these ipcores in ISE14.2, including axi_vdma and axi_datamover, there is the same problem when I want to simulate these ipcores.
I am very confused.
Thanks. I am look forward to your post.

I have not tried the datamover, but I know for certain that v5.02.a of the AXI VDMA synthesizes in 14.2 without issue.
When testing different versions of ISE on the same project, make sure you clean the project and allow the cores and prj files to be re-generated.

I also have verified correctness in ISE14.2, but why is not right in other ISE version?

It's a known issue. As mentioned, the tools weren't generating the correct .prj files in certain cases so it wouldn't grab all the necessary source code to compile the core.

i am facing this issue as well in ISE 14.7. The axi vdma core is of version 5.04a. Do you have any solution or workaroud for this issue?
Attached is the fuse.log for your references.
Kindly do advice and any help will be deely appreciates.
