Hi Altera Experts,
I've purchased a DE0-Nano Development Board and am attempting to compile the first example: https://www.physics.wisc.edu/undergrads/courses/fall2014/623/altera-deo_reference/de0-nano_my_first_fpga_v1.0.pdf The compilation has stalled at 83%. It is unclear, but it seems to be due to 'Unconstrained Paths' within the TimeQuest Timing Analyzer. The relevant log messages should be these: Warning (332087): The master clock for this clock assignment could not be derived. Clock: inst1|altpll_component|auto_generated|pll1|clk[0] was not created. Warning (332035): No clocks found on or feeding the specified source node: inst1|altpll_component|auto_generated|pll1|inclk[0] Warning (332060): Node: CLOCK_5 was determined to be a clock but was found without an associated clock assignment. Info (332154): The derive_clock_uncertainty command did not apply clock uncertainty to any clock-to-clock transfers. Warning (332056): PLL cross checking found inconsistent PLL clock settings: Warning (332056): Node: inst1|altpll_component|auto_generated|pll1|clk[0] was found missing 1 generated clock that corresponds to a base clock with a period of: 20.000 Warning (332061): Virtual clock CLOCK_5 is never referenced in any input or output delay assignment. Given that I am a complete beginner attempting my first example, can you please describe clearly how I can debug this? Are there further files that I should attach? Many Thanks, Will http://www.alteraforum.com/forum/attachment.php?attachmentid=13046&stc=1Link Copied

Hi Altera Experts,
I am eager for a reply. Let me know if there is a way I can improve my post to better allow for expert help. Thanks, Will- Mark as New

What operating system are you running on your computer?
What version of Quartus have you installed? Where did you get your demo software? Did you download it from the TerAsic suite, or is it from an included CD?- Mark as New

Per Altera's wbsite, the following are Quartus system requirements:
- Quartus 13.1 is the last version that will run on Windows XP 32b and Windows 7 32b (and it will run on Windows 7 64b also).
- Quartus 14.0 and later require Windows 7 64b (not 32b) and later (Windows 8.1).
- Quartus 16.0 is the first version supported on Windows 10 64b (also will run on Windows 7/8.1 64b).

Hi
Despite the OS compatibility issues, try a simple example first. A counter is a good starting point and see if it works. Then do a complex synthesis. Sometimes the synthesis process may last for hours depending on the design and FPGA capabilities. The TimeQuest warnings normally do not result in such situations.- Mark as New

Missing timing constraints or timing violation will usually not prevent design compilation. Please also tell what's the "first example" you tried to compile (design name).
