Assembler internal error Aria 10

[Altera_Forum]

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 wonder if there is some assembler parameter that has to be set...
