I have a problem with my design. It's not too complex (~7K LE), verified by modelling, successfully compiled and assembled, but I don't have timing due to internal Quartus error.

Problem Details

Error:

Internal Error: Sub-system: STA, File: /quartus/tsm/sta/sta_path_entry.cpp, Line: 4000

Reported slack does not match the slack calculated by the requirement: -720 reported, -617 expected
