[TimeQuest] How report clocks and missed Constraints?

[Altera_Forum]

Hi All, 

 How can I report clocks and missed constraints in TimeQuest?  Thank you

[Altera_Forum]

In the TimeQuest, is there a way to define the generated clocks automatically (like derived clocks)?

[Altera_Forum]

Generated clocks usually come from a pll, so the derive_pll_clocks command is what you use to define them automatically. 

If your clock signal comes directly from a fpga input pin or it is generated by a divider or any other method involving logic gates (but remember, it is a bad practice to create a clock signal this way) you have to define the clock manually, since TQ can't infer the clock period.  Regarding the first question, what's the problem? Reporting clocks and unconstrained paths are straightforward operations in TQ; these are the very first basic commands you should have leart.  Did you take a look at the tutorial?

How can I report unconstrained paths (clocks, etc)?

[Altera_Forum]

Look in the Tasks panel; you should see it on the left side of TQ window: in the Reports-Diagnostic section you'll find shortcuts for Report Clocks and Report Unconstrained Paths commands. 

 I tell you again: start with the TQ tutorial

Thanks Cris72 for your response!  

 When I click "Report Unconstrained Paths", the only Unconstrained Paths Summary appears (showing just a number of unconstrained paths), not the detail report (showing start/end points of unconstrained paths) - please see the attached snapshot.   So, how can I generate the detail report of the unconstrained paths?  Thank you!

Select the "Report" tab instead of "Tasks" in the bottom side of the left panel. 

Here you can view the details of unconstrained clocks and paths. In the main panel only the summary is showed

Thanks! My fault :-)
