Avalon ALTPLL generation error

Hi!

Come up against the next problem:

I'm adding simple Avalon ALTPLL module to my SOPC on a Stratix device using MegaWiz GUI. It contains inclk0, areset, c0 and locked ports. After module generation I recieve next message:

Info: Info: pll: Error while generating cbx_ALTPLL1300519856733329.tcl : 1 : Illegal port or parameter name clkena

Illegal port or parameter name extclkena

child process exited abnormally

Info: Info: pll: Illegal port or parameter name clkena

Illegal port or parameter name extclkena

child process exited abnormally

while executing

"exec clearbox altpll_avalon device_family=STRATIX CBX_FILE=cbx_ALTPLL1300519856733329.tcl -f cbxcmdln_1300519950827550"

("eval" body line 1)

invoked from within

"eval exec $cbx_cmd "

This error doesn't allow to generate SOPS system.

What may be the reason for such output?

And how to fix it?
