2.5.1. Specifying the Quartus® Prime Software Version

You can specify your version of the Quartus® Prime software in Implementation Options in the Synplify software. This option ensures that the netlist is compatible with the software version and supports the newest features. Altera recommends using the latest version of the Quartus® Prime software whenever possible. If your Quartus® Prime software version is newer than the versions available in the Quartus Version list, check if there is a newer version of the Synplify software available that supports the current Quartus® Prime software version. Otherwise, select the latest version in the list for the best compatibility.
Note: The Quartus Version list is available only after selecting an Altera device.
