Rise/fall time for general purpose outputs in MAX10 devices

Hello, I'm trying to find the rise/fall time spec for the general purpose outputs of MAX10 devices, but these data are unavailable in the data sheet. How I can know what is their typical value? Tha...

    Hi Valeri,


    The report_datasheet creates a datasheet report which summarizes the timing characteristics of the design as a whole. It reports setup (tsu), hold (th), clock-to-output (tco), minimum clock-to-output (mintco), propagation delay (tpd), and minimum propagation delay (mintpd) times. These delays are reported for each clock or port for which they are relevant.


    The Timing Analyzer uses advanced I/O timing and board trace model constraints to model I/O buffer delays in your design. If you want to check the 10-90 Rise/90-10 Fall time, you may refer to Input Transition Times / Signal Integrity Metrics.


    Thanks

    Best regards,

    KhaiY

Hi,


You may check this in Timing Analyzer by clicking on Reports >Datasheet > Report Datasheet.


Thanks

Best regards,

KhaiY

Thanks for reply, but I understand that the datasheet refers to the setup times relating to the clock, not the rise/fall time of each specific signal itself. So, the value I see is about 5-6ns - it's definitely not the rise time I'm looking for.

Again, I refer to the transition time from low to high and from high to low, typically from 20% to 80% of the max level

I found the Input Transition Times report in the Timing Analyzer>Advanced I/O Timing - does it give me the desired number? I'm a bit confused with a word "Input" as I'm looking for the output signals' rise/fall time

Thanks,

Valeri
