Why does Quartus® Prime Pro Edition version 25.1.1 and later add a phased_clk_lock_interface conduit to the altera_eth_1588_tod IP when targeting Agilex® 7 FPGA devices? - Why does Quartus® Prime Pro Edition version 25.1.1 and later add a phased_clk_lock_interface conduit to the altera_eth_1588_tod IP when targeting Agilex® 7 FPGA devices? Description In Quartus® Prime Pro Edition software version 25.1.1 and later, when targeting Agilex® 7 FPGA devices, the altera_eth_1588_tod IP exposes an additional phased_clk_lock_interface conduit. This interface conduit was not present in earlier Quartus® Prime Pro Edition versions. As a result, designs that were originally created and validated using Quartus® Prime Pro Edition version 25.1 or earlier may encounter connectivity issues or appear broken when migrated to newer software versions, due to the unexpected addition of this required conduit. Resolution To fix this problem in Quartus@ Prime Pro software version 25.3.1, install patch 1.23 below for the correct OS (Operating System) Readme: quartus-25.3.1-1.23-readme.txt Linux: quartus-25.3.1-1.23-linux.run Windows: quartus-25.3.1-1.23-windows.exe This problem is scheduled to be fixed in a future release of the Quartus@ Prime Pro Software.
