When I was running a timing simulation in Quartus Prime 20.1.1.720 Lite Edition, the progress is seems like to be stuck at there and not going to move anymore, below here is the last 2 sentence in the simulation log, really appreciate for any help
# MACRO ./Block1.do PAUSED at line 16

Determining the location of the ModelSim executable...
Using: C:\Simulation\modelsim_ase\win32aloem
To specify a ModelSim executable directory, select: Tools -> Options -> EDA Tool Options
Note: if both ModelSim-Altera and ModelSim executables are available, ModelSim-Altera will be used.
