Am I missing something stupid? When I try to place the altpll megafunction using the wizard I get:
"Megafunction altpll is not supported by the selected device family (Arria V)" Well, I guess I missed documentation about a new way of configuring the fractional plls. Can anybody give me a link? Quartus 12.1sp1 on Windows 7 64-bit Thanks.Link Copied

They use altera_pll now. Its best to generate the function from the wizard when migrating

Thanks. That was the pointer I needed. Is there a link to documentation on this somewhere?
I see the stuff in c:\altera\12.1sp1\ip\altera and I have added it to my project so I can get at stuff, but it would be nice to have a reference.- Mark as New

Also, for anyone who uses altera_pll, you're likely to trip over this bug in Quartus:
www.altera.com/support/kdb/solutions/rd10042012_164.html "Warning (332174): Ignored filter at <filename>.sdc: <hierarchy>.gpll~PLL_OUTPUT_COUNTER|vco1ph[0] could not be matched with a pin"
