Hi I get the following utilization in Fitter resource summary: that Clock pins - 3/2(150%) Dedicated Input pins 7/4 (175%) What does this exactly mean? Does this mean 3 clock pins are being used out of 2 and & dedicated pins are being used out of 4 But how can this be possible when there are 4 dedicated pins available or 2 clock pins available?? Is something going wrong?

It suggests your design needs more input resources than the device you've selected has available. Without a little more context the consequence of this is difficult to judge. What device are you targeting and, roughly, what is your design trying to do? Cheers, Alex

Thanks Alex The device I am using has more I/O pins and the design only needs one clock pin; the fitter is choosing these pins for some reason I can always change them in Pin Planner to other User I/O pins and make the clock and dedicated pin free. I mean if it is not coming as Error(red) should this be a problem I don't understand if the device has only available two clock pins how can it use 3??

How far through compilation does the project get? Can you post some of the report files generated when you run through project through Quartus? The "{}.sta.rpt" & "{}.fit.rpt" should do. It's not clear from what you've written whether there's an issue. The fitter may chose to use dedicated clock input pins for non clock signals. Cheers, Alex

Hi Alex Thanks very much. The compilation goes to 100 percent without error. I am not using any constraint files. I am using quartus ii 9.0 SP2 and I am not able to see any {}.sta.rpt file for some reason.Although I am attaching the {}.fit.rpt I/O pins ; 148 / 406 ( 36 % ) ; ; -- Clock pins ; 3 / 2 ( 150 % ) ; ; -- Dedicated input pins ; 7 / 4 ( 175 % ) Thanks very much for all your help

But I think 150% is more than 100%

Fitter resource usage summary

I get the following utilization in Fitter resource summary:

that Clock pins - 3/2(150%)

Dedicated Input pins 7/4 (175%)

What does this exactly mean? Does this mean 3 clock pins are being used out of 2 and & dedicated pins are being used out of 4 But how can this be possible when there are 4 dedicated pins available or 2 clock pins available??

Is something going wrong?

No not yet. Will do.

One more thing. I am not able to find EPF10K100 which is a Flex10K device anywhere. I tried no. of altera software including max plus 2 but the last Flex10K device that I see is EPF10K70??

Cheers
