2019.1 Synth Crash with VHDL 2008 generic package

Jump to solution

The synthesis crashes when using VHDL 2008 generic packages. There is a similar issue here.

I attached in minimal example.
Top module instantiating a generic package and a component "my_module". The component gets the package via a generic.

The package defines two constants, which are used in the component "my_module". There is a wrong assignment from the value of const_0 one to signal with a range from 0 to const_1. But the constants have the same value. Moving the constant's definition to the component, the synthesis success. Assigning the "correct" constant, the synthesis success. 

Have a look on the code and you will see, what I mean.

Synthesis crashes without any error message. I also attached the dump file for detailed debugging.

Regards
Christopher
