quartus simulation not working - quartus simulation not working Ive been trying to run a simulation on quartus, however I keep getting this error: I'm not sure what I'm doing that causes this error.

Replies: Re: quartus simulation not working There is a feature in quartus that can convert bdf to hdl. Can you simulate using hdl after converting the bdf? And see if Questa point to any of the lines? Replies: Re: quartus simulation not working There was no critical error during compilation. I used a block diagram so I'm not sure how I can look at the code to determine whats causing the error to occur Replies: Re: quartus simulation not working The error is clearly indicated what is wrong, could you please give snippet of the code? Any critical warning during compilation?
