how can i solve this question?please help me.

i use quartus6.0 and i modify the project:

e:\altera\kits\nios2_60\examples\vhdl\niosii_cycloneii_2c35\standard\standard.qpf

<div align='right'><{post_snapback}> (index.php?act=findpost&pid=19845)

You&#39;ve got to delete and re-generate in SOPC Builder. Also, there should be a script that removes any/all DDR settings/constraints from your QSF file, unless (of course) you&#39;ve already deleted that :-)

Hi,thanks slacker

According to your words,I do the following steps:

1) open the project

E:\altera\kits\nios2_60\examples\vhdl\niosII_cycloneII_2c35\standard\standard.qpf

2) delete the component DDR in SOPC ,then re-generate

3)in quartus,start full compilation,but find error message such as:

Info: Command: quartus_sh -t auto_verify_ddr_timing.tcl compile standard standard

Info: Quartus(args): compile standard standard

Error: Tcl error: can&#39;t find package ::ddr::settings

while executing

"package require ::ddr::settings"

(file "./verify_timing_for_ddr_sdram.tcl" line 54)

invoked from within

"source ./verify_timing_for_ddr_sdram.tcl"

(file "auto_verify_ddr_timing.tcl" line 11)

Error: Evaluation of Tcl script auto_verify_ddr_timing.tcl unsuccessful

Error: Quartus II Shell was unsuccessful. 2 errors, 0 warnings

Error: Processing ended: Wed Dec 06 15:40:01 2006

Error: Elapsed time: 00:00:02

Error: Quartus II Full Compilation was unsuccessful. 2 errors, 632 warnings

how an I do?

you should probably remove the constraint for ddr from the .qsf file. they are usually placed at the end of the file.

<div align='right'><{post_snapback}> (index.php?act=findpost&pid=19849)
