When quartus executes timing simulation, it calls Modelsim program error: Error:Can'tlaunch the ModelSim-Altera software

Error:Can’tlaunch the ModelSim-Altera software – the path to the location of theexecutables for the ModelSim-Altera software were not specified or theexecutables were not found at specified path.

Problem Description

• Call Modelsim program error when quartus performs timing simulation
  

---

solution:

• Solution 1: Correctly set the path of ModelSim in Quartus II Tools -> Options -> General -> EDA Tool Options: In the dialog box that appears, set the path to install ModelSim and must point to the folder where the ModelSim.exe file can be found
• Solution 2: Choose modelsim_alter instead of modelsim when you first start building the project. -Solution
  3: Open assignment-sittings-simulation-more EDA settings in Quartus18.1-the penultimate open OK)
