Error: DLL ("altpll_avalon") not found child process exited abnormally

Description

Due to a problem in the Quartus® II software version 12.0 SP2 and earlier, you may see this error, when generating your Qsys system containing an Avalon ALTPLL. This problem occurs when generating Qsys systems on 64-bit Linux platforms.

Resolution

You can use one of the following solutions to resolve this issue.

1 . Generate your Qsys system using Quartus II Windows 32-bit Linux system or a PC.

--Or--

2. To use Quartus II Linux 64-bit software, take the following steps:

·        Locate the sopc_mwizc.tcl file at the following Quartus II installation directory path.          {rootdir}/12.1/ip/altera/sopc_builder_ip/altera_avalon_mega_common/sopc_mwizc.tcl

·        Around line 894, delete the following line:

set cbx_cmd "clearbox device_family= CBX_FILE= -f "

·        Replace the above line with following code

# construct the path to the 32-bit version of clearbox,

# to match the presence of 32-bit shared libraries being

# present in the LD_LIBRARY_PATH.

set qrootdir $::env(QUARTUS_ROOTDIR)

set os_platform $::tcl_platform(os)

if { [string equal -nocase -length 3 "lin"] } {

set bindir "linux"

} else {

set bindir "bin"

}

set cbx_cmd "//clearbox device_family= CBX_FILE= -f "

 

·         Close and re-start Quartus II (if already open). Try Qsys generation.

This issue is fixed beginning with the Quartus II software version 12.1.
