Instance instantiates undefined entity

Altera_Forum · ‎07-03-2012

I have a project using the VIP scaler II. I am able to build it using the Quartus 11.1sp2 GUI on Ubuntu Server 11.04 64bit. The GUI build runs fine, but a command line build errors out during map with several errors all surrounding the scaler II IP:


Error (12006): Node instance "video_in" instantiates undefined entity "alt_vip_video_input_bridge" File: /var/tmp/build/vpb_0703121305/alt_vip_cl_scl_0002.v Line: 517

I have the following in my bashrc:


ALTERA_VERSION="11.1"
QUARTUS="/opt/altera/$ALTERA_VERSION/quartus/bin"
QUARTUS_ROOTDIR_OVERRIDE="/opt/altera/$ALTERA_VERSION/quartus"
SOPC_BUILDER="$QUARTUS_ROOTDIR/sopc_builder/bin"
SOPC_KIT_NIOS2="/opt/altera/$ALTERA_VERSION/nios2eds"
QUARTUS_64BIT=1
export LM_LICENSE_FILE
export QUARTUS
export QUARTUS_ROOTDIR
export SOPC_BUILDER
export SOPC_KIT_NIOS2
export QUARTUS_64BIT
export PATH="$PATH:$QUARTUS:$SOPC_BUILDER:$SOPC_KIT_NIOS2/bin"

I must be missing a link to a library that the GUI is using. Anybody have any ideas?

is an x display present when doing the command line build? or are you just ssh'd into the box?

I'm using X forwarding over SSH.

i am not sure if that is sufficient to satisfy java's requirement for the presence of an xdisplay. It may be, but i am not sure. A bunch of the ip generation tools are written in java, including qsys.

generally, what i do when running over a shell is setup a vnc session locally

It should be okay. I've had this working in version 10.1sp1 but I've recently migrated to 11.1sp2 with the intention of migrating the design to Qsys afterwards.

I think I figured out what was going on. I have a makefile copy my project files and source to a new folder under /var/tmp/<user>/ and automatically update a revision register before kicking off the build. Apparently, Quartus stores your IP search path under /home/<user>/.altera.quartus/ip/<quartus version>/ip_search_path/user_components.ipx. Note the <quartus version> folder. Having just migrated to 11.1sp1, my search path wasn't stored there. Now, that doesn't explain why it bombed on synthesis of the scaler II, but I did just migrate from scaler I to scaler II, so I have multiple things going on.

The other issue is that we have all the project files and source stored in SVN. We occasionally build the project in Windoze depending on who does it.

We'll see how this build pans out.

Same thing.

Local command line builds under my project directory work fine, but the makefile builds that copy the project files and source are now bombing out on the scaler II modules. The only way I'm finding around it is to rerun sopc_builder in the new directory under /var/tmp. However, running it with --generate appears to complete fine, but it exits with an error so my makefile stops after that.
