Hello, we are installing quartus19.4 pro linux version it showing the option of different different soc and fpga latest version but we want to add cyclone v se in pro version so how we can add the soc cyclone v se. please tell us as soon as possible..

Cyclone V (all variants) is only supported in Standard edition, not Pro, so you'll need to install Standard and the Cyclone V device.

#iwork4intel

but in 19.4 linux ver is not avilable in standard ver

Is there a feature or something in the newer version that you need? For Cyclone V SoC, 19.1 should be sufficient.

#iwork4intel

Yes, you can also look into the release note to see what is the improvement feature for different release.
