Description

I've added the sample/sample.vhd VHDL design to project test suite. When I run Retrascope with the following parameters:

src/test/vhdl/sample/sample.vhd --target test --toplevel sample --engine efsm-fate-test-generator --loop-limit 25

I receive an error with the following log:

I've tried to compile the sample.vhd on ModelSim and GHDL simulators and they have said that it is ok.
