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?

Richard Tan

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 10
Quartus: Quartus Standard 23.1 Build 991.
I would recommend using HDL instead of schematics because as the design gets complicated, it becomes messy quickly.

Yes, indeed block diagram/schematic (.bdf file). On another, a bit older, laptop also running Win10, it is working ok.
If I open another design, sometimes, very sometimes, the clipboard is filled and paste is not greyed out. But only for larger selections, it still does not work. It seems to me some process/service/policy is preventing the clipboard to be filled, but I do not have the knowledge of all processes that are running.

It will be challenging for me to debug the issue as it is not replicable from my side. Your best bet is to attempt some troubleshooting steps and, hopefully, identify the root cause.
Here are troubleshooting steps that you may check:
1. Before you download and install the software, please check that your machine System and Software Requirements are meet before installation. Ensure that your Operating System is supported.
2. Install currprocess https://www.nirsoft.net/utils/cprocess.html and disable all the software running behind.
3. Try restarting Quartus and your computer. This can help clear any temporary issues that may be causing the error.
4. Check your system resources, including memory, CPU usage, and disk space. Make sure you have enough available resources to run Quartus.
5. Try disabling any antivirus or firewall software temporarily, as they may be interfering with Quartus.
6. Try to re-download the Quartus .tar installation package and install again. Check that the installation files .tar is not corrupted by checking the checksum.
7. Make sure that your quartus directory folder are not in read only options.
8. Google for related issue on clipboard copy and paste. Here an example:

Hi Richard,
Thanks for your support. I was on holidays, so my response was delayed.
I have tried all proposed solutions, except disabling the virus scanner (I have no rights to do so). I will ask our IT support to try this.
My machine is a Dell Latitude 5431 with 16Gb RAM and plenty disk space left. 12th gen i5-1250P core, running Win10 Enterprise 22H2.

Still waiting for support from our IT department.
The strange thing is that I can sometimes copy paste single wires.
Circuit blocks or multiple wires can never be copy-paste.

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?
