ModelSim - incorrect output

I'm following the ModelSim_GUI_Introduction.pdf. On page 16 of the pdf file, I couldn't get the correct output for both Figures 25 and 26. Please find attached the screenshot of the waveform input,...

Hi Chow,

Sorry I was referring to this old doc http://195.130.74.161/ModelSim_GUI_Introduction.pdf but it is the same thing. According to your doc Figure 25 and 26 is same thing. Your output is y and x1,x2,x3 is just inputs. What I gave you is based on your attached simulation for second picture, the functionality worked as the truth table meaning it is correct. Also based on your doc, Figure 28 is the new simulation output for y to play around with your input x1,x2,x3 by changing their state to high or low for certain period cycle. The fact that you design work is good already :)

Thanks,

Best Regards

Thank you.

May I ask another question?

How do I open the wave file (.do) that I saved in earlier project?

For example, I saved this yesterday, but I couldn't open these inputs of x1,x2,x3 that I have keyed in for the simulation yesterday.
