Modelsim error on altera_onchip_flash_block - Error: (vsim-3033): Instantiation of 'altera_onchip_flash_block' failed. The design unit was not found.

Hello. I'm trying to simulate project with getting data from OnChipFlash. I'm using the Lite edition of Quartus 17.0.2 and ModelSim - INTEL FPGA STARTER EDITION 10.5b. I create testbench file to s...

    You make the AC_meas_tb as the testbench. Can you check inside the AC_meas_tb.v files, what is your module name there? currently, the tools are complaining the testbench issue.

KennyT_Intel, I ask you to answer one more question:

If I modify a file in the project, then to restart the simulation with the new data, I first stop the simulation "quit-sim" and recompile with the commands "source msim_setup.tcl" and "LD", but modelsim gives a lot of errors on each external module used by top-level file MAIN.v:

# Loading work.main

# ** Error: (vsim-3033) ./../../../main.v(198): Instantiation of 'receiving_from_PC' failed. The design unit was not found.

# Time: 0 ps Iteration: 0 Instance: /AC_meas_tb/main_inst File: ./../../../main.v

etc.

If I quit from ModelSim and start it again, do all operations described above, simulation start again normal.

How restart simulation without reopen ModelSim?
