vivado Reset Behavioral Simulation后，无法运行仿真问题解决

问题描述

vivado Reset Behavioral Simulation后，运行仿真显示以下问题。但是verilog代码以及test bench文件无bug，且错误日志里也没有记录。

ERROR: [USF-XSim-62] ‘compile’ step failed with error(s) while executing ‘C:/fpgaprogram/ADS8688_driver_test/ADS8688_driver_test.sim/sim_1/behav/xsim/compile.bat’ script. Please check that the file has the correct ‘read/write/execute’ permissions and the Tcl console output for any other possible errors or warnings.
ERROR: [Vivado 12-4473] Detected error while running simulation. Please correct the issue and retry this operation.
ERROR: [Common 17-39] ‘launch_simulation’ failed due to earlier errors.

原因分析

经过查看，在Tcl Console显示以下错误

ERROR: Could not find 64-bit executable.
ERROR: C:/Xilinx/Vivado/2018.3/bin/unwrapped/win64.o/xvlog.exe does not exist

解决方案：

检查360是否误删文件，恢复后仿真能重新运行
