Cannot select specific target device - Cannot select specific target device Hi, I am using Quartus Prime 18.1 build 625 I cannot change the target device I am compiling to. It will not allow me to select a specific FPGA, it only chooses the default Cyclone V FPGA. The options to change are grayed out; I included a screenshot to show you all. Does anyone know of a way to fix this? Replies: Re: Cannot select specific target device I’m glad that your question has been addressed. With that, I will now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.

Replies: Re: Cannot select specific target device Same suggestion with sstrell, I would reinstall the latest Quartus Standard version 21.1.

Can you try reinstalling the .qdz file for Cyclone V devices (or maybe delete and completely reinstall Quartus)?
