I'm using Quartus Prime Pro Edition, version 20.2.0 Build 50 06/11/2020 SC Pro Edition with "Patches installed: 0.27fw".
When in the Platform Designer I select the IP "SPI Slave to Avalon Master Bridge Intel FPGA IP" and click on "Documentation" and then "User Guide", my browser reports a broken link.
Attached see screen shot showing the link address.
Presumably, the link to the User Guide goes to "documentation.altera.com/....." but that host name no longer exists.
I believe it is several years since Altera was acquired by Intel, so all links to user guides and release notes should be updated.
