in Qsys 11.1sp1 i added an Avalon ALTPLL, connected the inputs to clk_0, set all the outputs to conduits, and was able to generate the system

i took the first command from your log that looks like it throws up:

C:\temp>clearbox altpll_avalon device_family=STRATIXIV CBX_FILE=PLL_playground_a

ltpll_0.v -f cbxcmdln_1326246500574197

Error in generator - aborting

ERROR : MGL_INTERNAL_ERROR: Illegal module name UNUSED. Module name UNUSED is no

t a submodule of altpll_avalon

ERROR : The width_clock of 6 specified is not supported in STRATIXIV

can you delete the Avalon_ALTPLL and reinstantiate it?
