i was just practicing basics in vhdl with vivado. i wrote a simple when else staement , the synthesis worked perfectely but when i ran behavorial simulation i got following error
ERROR: [Common 17-39] 'launch_simulation' failed due to earlier errors
this is what i found in the Tcl console.
ERROR: [USF-XSim-62] 'compile' step failed with error(s). Please check the Tcl console output or 'C:/Users/manishpatkar/when_else/when_else.sim/sim_1/behav/xvhdl.log' file for more information.
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.
i checked the folder C:/Users/manishpatkar/when_else/when_else.sim/sim_1/behav/xvhdl.log and it had

I am trying but not able to find what caused did! someone please help!
