will Cyclone III work with unconected VCCA PLL ??

I made some simple logic which routs clock signal to output pin, I have on board 16mhz clock and I got much lower frequency clock signal about 1Mhz, and I changed PLL clock presscaler and got different results so I must say that chip don't work stable with one VCCA1 pin connected and other VCCA2 unconnected.

but at least it configures :)

also I noticed that I cant see clock signal on output pins without using PLL by directly connecting clock signal to internal logic clock signal(I had 16bit counter for clock division), and there was no signal output pin, also tried to rout clock signal in global line and still no results, I had results just with using PLL.

so I guess I will have to drill one more hole and solder VCCA2 pin :(
