Internal Error: Sub-system: TDC, File: /quartus/tsm/tdc/tdc_accessories_delay_budget.

Anyone found a way to avoid hitting this internal error?

I've been hitting it more & more frequently, and can't seem to avoid it any longer. Since it takes ~45 mins for the build to get to the point where it hits this (& dies), it's eating a lot of my time.

Internal Error: Sub-system: TDC, File: /quartus/tsm/tdc/tdc_accessories_delay_budget.cpp, Line: 1991

    Hi Briane,

    I'm sorry that you're hitting this error - I'm part of the team that owns this code. Can you please submit an SR that includes a QAR of your design at https://www.altera.com/myaltera?

    Cheers, Adrian

    Hi Adrian, thanks for the quick reply. It's SR# 10795756, and has a full 'service request w/ incremental database' qar attached so it will hopefully be easy for you to reproduce. Thanks & good luck. I'll keep my fingers crossed for a workaround. ;) -Brian

    Hi Brian, we couldn't reproduce this on a 64-bit Windows build. What OS and build (32 or 64 bit) were you using?

    Also, note that this is compiled without a megacore ip license for the rapidio (in case that affects the generated IP timeout logic & affects your reproducibility).
