Specifies the device family for the device you want to select or you want the Compiler to select for compilation. A device family appears in this list only if you install support for at least one device in the family in your copy of the Quartus® II software. Contact Altera® Applications or go to the Device Support page, which is available from the Support section of the Altera web site for more information on installing device support.
When you select a device family, the Available devices list in the Device page of the Settings dialog box (Assignments menu) displays available devices from that family.
If you specify the ACEX® 1K, APEX™ 20K, APEX™ II, ARM®-based Excalibur™, Cyclone™, FLEX 10KE, Mercury™, Stratix™, or Stratix™ GX device family for compilation, the Compiler has only one level of effort when optimizing timing, and therefore the Optimize timing list under Timing-driven compilation in the Fitting page in the Settings dialog box (Assignments menu) is dimmed to indicate that it is not available.
If you specify the FLEX® 6000 device family for compilation, the Optimize I/O cell register placement for timing option under Timing-driven compilation is dimmed to indicate that it is not available.
If you specify the MAX® 3000 or MAX 7000 device family for compilation, the options under Timing-driven compilation are dimmed to indicate that they are not available.
