Timequest for asynchronous design

You don't mention what x and y are (ports, pins?) but the main command to use is report_timing. It should look something like this:

report_timing -setup -from [get_[pins/ports] x] -to [get_[pins/ports] y]

Hi,

Does the design contain any registers? You can see the delay for a combinational logic between registers by reporting the timing between the registers. The Timing Analyzer recognizes and analyzes the following timing paths only.

• Edge paths—connections from ports-to-pins, from pins-to-pins, and from pins-to-ports.
• Clock paths—connections from device ports or internally generated clock pins to the clock pin of a register.
• Data paths—connections from a port or the data output pin of a sequential element to a port or the data input pin of another sequential element.
• Asynchronous paths—connections from a port or asynchronous pins of another sequential element such as an asynchronous reset or asynchronous clear.

Thanks.

​Hi,

Thank you for your answer.

So if I don't have any register there is no way to know delays between luts?

report_timing gives the same:

"Report Timing: No setup paths were found"

Best regards

report_path should be able to do what you want. Just make sure you use the correct filter as what sstrell mentioned
