SOPC Builder hangs on Linux when generating UP IP

[Altera_Forum]

I have installed Quartus 8.1 with NIOS and SOPC in Ubuntu 9.04. I can compile, program the DE2 board, an so on (thanks to many mesages from this forum). I have run also the SOPC demo without problems. 

 I would like to use University Program IPs for DE2 board. I have download zip versions from Altera, installed the components, and set the path to include them in SOPC (I only found a windows installer). They are recognized, and I can include and configure them from the SOPC GUI.  The problem is that SOPC Builder "hangs" when trying to generate any UP component (I have to manually kill the process).  I have already tried: - Refresh components and system from SOPC. - Generate *.ipx (even moving the UP components to where the main sopc_builder components are, that is /opt/altera8.1/ip/altera/sopc_builder_ip).  If someone can give me a clue about why I'm missing...

More info on topic. After contacting Altera, they say that Ubuntu is not supported. However, error does not seem related to Ubuntu, because if I run SOPC for non University Pogram components it works perfectly. 

 Anyway, If I run: > sopc_builder --generate nios_system --debug  then a warning is output before SOPC hangs.  (snip) Progress: (validating nios_system) Progress: current 955:  Progress: current 954:  Progress: (done reading nios_system) Progress: Validating... Progress: Generating /home/jordi/vhdl/DE2_exemples/DE2_JRB_Demo/nios_system.sopc Warning: Switches: PIO inputs are not hardwired in test bench.

More on this topic. 

 After debugging the *_hw.tcl files for UP components, I found that their are prepared for windows only. So, the basic problem consists on files or paths which are not found.   I could avoid the complete hang of SOPC builder by issuing these commands:  sudo ln -s $QUARTUS_ROOTDIR/linux/perl $QUARTUS_ROOTDIR/bin/perl sudo ln -s $QUARTUS_ROOTDIR/linux/perl/bin/perl $QUARTUS_ROOTDIR/linux/perl/bin/perl.exe  which create symbolic links for the expected executables in *_hw.tcl.   However, there are still more problems to solve. Now I've got errors like:  Info: Wrote /home/jordi/vhdl/DE2_exemples/DE2_JRB_Demo/nios_system.sopcinfo Info: nios_system: Wrote /home/jordi/vhdl/DE2_exemples/DE2_JRB_Demo/nios_system.html Info: sram: Starting Generation of SRAM or SSRAM Controller Error: sram: Generation callback did not provide a top level file (expected `add_file sram.v/vhd/sv {SIMULATION SYNTHESIS}`) Info: keys: Starting Generation of Parallel Port Error: keys: Generation callback did not provide a top level file (expected `add_file keys.v/vhd/sv {SIMULATION SYNTHESIS}`) Info: vga: Starting Generation of VGA Error: vga: Generation callback did not provide a top level file (expected `add_file vga.v/vhd/sv {SIMULATION SYNTHESIS}`) Info: vga_char: Starting Generation of Character Buffer Info: vga_char: /opt/altera9.0/quartus/bin/perl/bin/perl.exe -I/opt/altera9.0/quartus/sopc_builder/bin/perl_lib/ UP_IP_Core_Generator.pl lang=vhdl outdir=/home/jordi/vhdl/DE2_exemples/DE2_JRB_Demo/ name=vga_char files=Altera_UP_Avalon_Character_Buffer.v;Altera_UP_128_Character_Rom.v;Altera_UP_FB_Color_Rom.v;Char_Mode_Rom_128.mif;FB_Color_Rom.mif params=AW:13;DW:8;BUFFER_SIZE:8192;ENLARGE_CHAR:0 sections=USING_DE1:0;USING_FOREGROUND_COLOUR:0;USING_BACKGROUND_COLOUR:0;USING_1BIT_COLOUR:1;USING_4BIT_COLOUR:0;USING_8BIT_COLOUR:0;USING_9BIT_COLOUR:0 Error: vga_char: Generation callback did not provide a top level file (expected `add_file vga_char.v/vhd/sv {SIMULATION SYNTHESIS}`) Info: vga_pixel: Starting Generation of VGA Pixel Buffer Error: vga_pixel: Generation callback did not provide a top level file (expected `add_file vga_pixel.v/vhd/sv {SIMULATION SYNTHESIS}`)  I suppose it is related, so there should be an executable/path missing somewhere. If anyone has experience with callback functions, he/she may be of great help.  UPDATE: I've got an answer from Altera regarding the last errors. It seems that they are aware of the errors (so, I suppose it is also the same with windows Quartus 9.0 and UP cores) and they promise to release an updated version of the cores this week. :)

The new UP cores for 9.0 are available for download on the Altera ftp site at: 

ftp://ftp.altera.com/up/pub/university_program_ip_cores/90/  I've done a basic test and they build nicely on my Ubuntu system.  So, it seems that this problem is finally solved.
