Remove Nios referenced files from project no longer using Nios

[Altera_Forum]

Hi. 

I am facing the following problem. I recently remove the Nios from a design, and somehow the project still try to references some files, I have tried to search in the .qsf file but there is no references there anymore. even in the timquest while generating the netlist I am getting this warnings.  do anyone knows what files I should remove or modify so that the current project is no loger sending warnings for missing files?   Info: ******************************************************************* Info: Running Quartus II TimeQuest Timing Analyzer  Info: Version 9.1 Build 222 10/21/2009 SJ Full Version  Info: Processing started: Wed Aug 18 15:40:33 2010 Info: Command: quartus_sta DEU_H_Projekt -c DEU_H Info: qsta_default_script.tcl version:# 2 Warning: Can't find design file cycloneiii_3c120_dev_niosii_standard_sopc.v Warning: Can't find design file altmemddr.v Warning: Can't find design file altmemddr_controller_phy.v Warning: Can't find design file altmemddr_auk_ddr_hp_controller_wrapper.v   also the qsta_default_script.tcl is not found anywhere. where can it be? is this the one making all this trouble  for your help.. thankyou.

Yeap! as inusual as it sounds. 

by reading the warnings of the project I found that some say,  XXX file not found... and  some constraints ignored while trying to reach a instance of a component which is no longer in the design.  Update: I was able to remove many of them, by Project-->Organize Quartus Setting File. Saving the project.. AND Closing Quartus completely... removing db and incremental_db Reopening the project. Recompile all.  However there still some references that still try to reach some old components.

Are there any old qip files that are still included in the project?

I agree with kevin.

[Altera_Forum]

I would like to agree with you both, but there is no qip on the project. it is allready removed.

could it be related to the ip cache?

I did not find the cache, however I dont have any error on compiling, it is just the warnings. What I did. I remove completely the folder and fetch it again from my repository (svn) which includes only the needed source files. and no automaticaly generated files. 

 then I solve the previous problem.  Now I still have some other linkages, to some other entities no loger existing. See Below. I will try to do the same procedure again to se if this time it is solved. Any other ideas where are this "global assignments set?" I allready look in the qsf file and there are no "OPTIMIZE_POWER_DURING_SYNTHESIS NORMAL_COMPILATION" options there.   Warning: Found invalid Fitter assignments. See the Ignored Assignments panel in the Fitter Compilation Report for more information. Warning: Ignored assignments for entity "altsyncram_3ua1" -- entity does not exist in design  Warning: Assignment for entity set_global_assignment -name OPTIMIZE_POWER_DURING_SYNTHESIS NORMAL_COMPILATION -entity altsyncram_3ua1 -tag quartusii was ignored Warning: Ignored assignments for entity "altsyncram_94m1" -- entity does not exist in design  Warning: Assignment for entity set_global_assignment -name OPTIMIZE_POWER_DURING_SYNTHESIS NORMAL_COMPILATION -entity altsyncram_94m1 -tag quartusii was ignored Warning: Ignored assignments for entity "altsyncram_a3m1" -- entity does not exist in design  Warning: Assignment for entity set_global_assignment -name OPTIMIZE_POWER_DURING_SYNTHESIS NORMAL_COMPILATION -entity altsyncram_a3m1 -tag quartusii was ignored Warning: Ignored assignments for entity "altsyncram_aai1" -- entity does not exist in design  Warning: Assignment for entity set_global_assignment -name OPTIMIZE_POWER_DURING_SYNTHESIS NORMAL_COMPILATION -entity altsyncram_aai1 -tag quartusii was ignored Warning: Ignored assignments for entity "altsyncram_e2m1" -- entity does not exist in design   Thankyou!

Are you sure you had removed the file paths from SETTINGS/FILES? That path is still included even if you have deleted the file.
