Where could I get new patch or license for N3000 IP？

You will need to re-download the 1.3.1 Acceleration Stack for FPGA Development and re-install the package. The file is available from: https://www.intel.com/content/www/us/en/programmable/products/boards_and_kits/dev-kits/altera/intel-fpga-pac-n3000/getting-started.html

If you untar the latest 1.3.1 N3000 file - n3000_ias_1_3_1_pv_dev_centos_installer.tar.gz You will see the following contents:


$ ls -al
total 8942084
drwxrwxr-x. 3 user user 100 Jan 6 13:12 .
drwxr-xr-x. 11 user user 8192 Jan 7 06:25 ..
-rw-rw-r--. 1 user user 218965 Jan 6 13:11 config_4.19_opae
-rwxrwxr-x. 1 user user 9156457935 Sep 10 11:25 n3000-1.3.8-4-dev-el7-setup.sh
drwxrwxr-x. 2 user user 44 Jan 6 13:12 N3000_supplemental_files

The file "n3000-1.3.8-4-dev-el7-setup.sh" contains the updated installer with new license files with 31-dec-2027 expiration.

By default the installer will remove the existing /inteldevstack, so if the user wants to preserve this directory, then mv the /inteldevstack directory to another location before running the installer.

The command to install just the N3000 Quartus Pro and license is:

$ sudo ./n3000-1.3.8-4-dev-el7-setup.sh -y -t quartus source --owner <user[: group]>
