We are using Quartus 23.3.pro and copy paste function is not working with it. If I open another Quartus window with another design, cut and paste sometimes(*1) works, but only for single blocks, Not for larger selections. I can also paste the single block in the other quartus window (the window where cut and paste never works). But after the paste action, I cannot cut and paste that block again in any window.

Is a "block" here just code (aka text) or are you trying to copy/paste something else? There's no schematic editor in recent versions of Pro so I don't know if you are talking about a schematic or something else.

Are you copying and pasting text from a text editor window, such as copying RTL code from one .v file to another? If so, I don't see any issue with copying and pasting multiple times.Could you check whether this issue only occurs with Quartus software and does not impact other applications, for example, Notepad+?You might need to restart your machine and see if the issue still persists.More description of the issue and steps to duplicate it are needed as well. Also, which operating system does Quartus run on?Regards,Richard Tan

Any update or progress on the issue?

The issue HituS is describing is with Quartus Prime Lite v23.1std.In the schematic entry window a copy and paste does not work. The copied items do not appear on the clipboard and thus cannot be pasted.All other applications work fine. Also text copy in Quartus works fine. The issue is only with schematic entry.

I assumed you are referring to the block diagram/schematic file(.bdf file). I tried and able to successfully cut and paste the block in the same/ different .bdf file.Make sure when you try to cut the block, you need to click at a blank space first before paste the block.OS info: Window 10Quartus: Quartus Standard 23.1 Build 991.I would recommend using HDL instead of schematics because as the design gets complicated, it becomes messy quickly.Regards,Richard Tan

We've tried all suggestion above. Nothing seems to work.
One day, for a short moment, things were working fine again. Copy and paste worked fine.
But after 5 minutes things stopped working again and have not worked since then.
I think something is blocking the clipboard from being filled, but have no idea what.
Can there be any (group) policy installed on my machine that does something with the clipboard?
