Hi,
What is your interconnect usage? Designs with an average value below 50% typically do not have any problems with routing. Designs with an average between 50-65% may have difficulty routing. Designs with an average over 65% typically have difficulty meeting timing unless the RTL tolerates a highly utilized chip. Peak values at or above 90% are likely to have problems with timing closure; a 100% peak value indicates that all routing in an area of the device has been used, so there is a high possibility of degradation in timing performance.
Thanks.

find the interconnect usage as below:
Average interconnect usage (total/H/V) 50.7% / 48.7% / 57.0%
Peak interconnect usage (total/H/V) 80.4% / 81.7% / 86.1% - Yogesh5 years ago

Hi Khai,

Peak interconnect usage (total/H/V) 80.4% / 81.7% / 86.1%
Since average interconnect is less it should not cause any problems in routing right ?
But 8 out of 10 times fitter terminates because of routing congestion.
Is there a way to find which module has high interconnect usage ? So that I can change the coding style and improve timing .- KhaiChein_Y_Intel5 years ago

Hi Yogesh,
Yes. There is a way to check which module uses most of the routing resources.
Thanks.

Hi Khai,
I think the screenshot you shared is for quartus pro edition. I am using intel quartus standard edition 18.1
I find only routing usage summary under logic and routing section ,which only talks about resources like Block interconnects
C12 interconnects
C2 interconnects
C4 interconnectsand not about module level usage . Is there someother option to check the same w.r.t each module of my project?
thankyou
regards,
Yogesh
