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.
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.
