and then our old simulation setup (based on modelsim) was able to simulate them just fine, but I can't get this one to work in VUnit, I assume there may be something unique about it, and that it's not a general problem with all *_sim_netlist.vhdl files, however I don't know th...

There are many ways to create a shift register in VHDL, though not all of them are equal. You can dramatically reduce the number of consumed resources by choosing the right shift register implementation for your needs and FPGA architecture. A shift register implements a FIFO of fixed length. ...
