Assembler internal error Aria 10

Hi,

I experience a crash during assembler stage for my design. Attached is the report generated by Quartus.

As far i can understand there is an issue with some constraints regarding the IOPLL ip that i use.

For the same design the assembler had worked fine before i included an IOPLL ip (very simple pll : one refclk one output, all else defaults)

in the constraints i just include 'derive_pll_clocks' and 'derive_clock_uncertainty commands.

anybody had similar problem before? i saw some issues with Aria 10 in Quartus but i don't think this is my problem as without the IOPLL i could get a sof file...

    Thats a tool crash - you'll have to raise a mysupport ticket to find out the cause.

    Have you tried using Q16 instead of 15?

    I think i will ask the support , it is just weird because with the similar design and another (more complex) PLL it doesn't crash. I wonder if there is some assembler parameter that has to be set...
