Blog: Windows ate my Signal Browser

Well, it’s been a strange few weeks hasn’t it?

Well, it’s been a strange few weeks hasn’t it? I don’t know about you, but whilst in lockdown I’ve not had much to do at the weekends, so have used the opportunity to watch some old films. As we haven’t been able to go to any of the excellent local eateries either, a few culinary films came to mind; ‘How to Eat Fried Worms’, ‘We’re Going to Eat You’ or maybe more appropriate for the current climate ‘In China They Eat Dogs’. Although, perhaps 90’s Danish action comedy isn’t your thing…

Maybe a recent support call from an Aldec Active-HDL user also has something to with my sudden interest in food related films too? Their problem was that when running simulations, the signal browser had been mysteriously “eaten” by something!

Could this be due to the latest Windows Update? Below, you can see the problem the user had experienced (on the left), alongside an example of how the window should have appeared (on the right).

Do not worry, I have seen this before and for once it’s not actually a Windows issue. In fact, the signal browser had not been eaten by anything at all… In this case it was simply that the window has been resized too small to be visible, an issue that is easily fixed by running Perfman.exe from the Aldec Active-HDL installation Bin folder.

If you have experienced similar issues to this, or just want some guidance on setting up Active-HDL, why not have a look at my recent ‘Aldec Active-HDL Waveform Display hint’s and tips’ blog, where you will find more on Perfman.exe as well as some other help full tips.

Keep well over the coming weeks, till the next time!
