I am trying to run a simple project consisting of 3 logical gates. However, after succesfully compiling the project, when I try to run the WaveForm, the project fails and displays the following error:

# do Circuito1.do

# ** Warning: (vlib-34) Library already exists at "work".

# Model Technology ModelSim - Intel FPGA Edition vcom 2020.1 Compiler 2020.02 Feb 28 2020

Error.

I don't know if this is the issue for sure, but there are spaces in your directory path ("Semestre 7" for example).  Try a directory with no spaces.

Hi, does the Strell's suggestion helps? Do you need further help on your case?
