Compile - Error (10481): VHDL Use Clause error at auk_ddr_controller.vhd(35):

[Altera_Forum]

Hey, sorry, I just want to bring this over to the IP Discussion forum. Problem is here: 

 http://www.alteraforum.com/forum/showthread.php?t=4665 (http://www.alteraforum.com/forum/showthread.php?t=4665)  I'm trying to compile the PCIe to DDR2 reference design and Quartus gives the following error: Info: Found 2 design units, including 1 entities, in source file auk_ddr_controller.vhd Info: Found design unit 1: auk_ddr_controller-rtl Info: Found entity 1: auk_ddr_controller Error (10481): VHDL Use Clause error at auk_ddr_controller.vhd(35): design library "auk_ddr_lib" does not contain primary unit "auk_ddr_functions" Error (10800): VHDL error at auk_ddr_controller.vhd(35): selected name in use clause is not an expanded name  Since the whole mess is generated by the DDR2 controller MegaFunction and presumably brought in all the settings when I converted from the 7.1 to the 8.0 SP1 Megacore IP, I'm not sure how to proceed.  Thanks for your help.   Leslie

Try deleting the db directory and recompiling.

I am seeing the same problem. I just downloaded Quatrus II 9.0 and tried to build nios2eds\examples\verilog\niosII_cycloneII_2c35\low_cost. I got exactly the same error. I tried renaming the nios2eds\examples\verilog\niosII_cycloneII_2c35\low_cost\db directory and no change. 

 I am running the Quatrus Web edition 9.0 on Vista.   Any ideas?

I'm sure it did. However, the designer probably still had 7.2 installed on his/her computer. Some of the megafunctions were from 7.2 and still referenced the old path. So they wouldn't compile on my computer. The error message was fairly cryptic.  Hmmm, maybe I also had to add a library to the project... the 7.2 megafunctions were archived in a subdirectory but I didn't notice until I'd already taken the other approach.  I can't guarantee that's your problem, too, but it's worth a shot. Try recompiling or recreating the megafunctions in your design.

Cool, 

Same error I'm getting (not using Vista). I am trying to compile an example problem so it sound like I have to locate the line in the code that is referencing a none existent link and substitute in a correct link for Quartus 9.0...

Can someone please instruct me on how I would "recompile or recreate" the megafunctions to work with 9.0 and my DE2_70 Development board?    Thanks a ton in advance!   -Jorden

I just tried to recompile C:\altera\90sp2\nios2eds\examples\vhdl\niosII_cycloneII_2c35\standard 

With Qaurtus(+Nios) 9.0sp2 And I get same error although ddr_sdram_controller-library is in Project libraries (already in Assignments settings).  I success compiling by :   backup the altera example first !  * removing db, incremental_db folders  * regenerating SOPC (with Sopc Builder)  I have warning messages. I don't sure it is working good
