Fitter resource usage summary

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?

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.

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

to me it is a reporting bug, unless tool has got super clever and we can't spot it. But I think 150% is more than 100%

Thanks Kaz 

 

Alex, however I am attaching {}tan.rpt (timing analyser report) instead of {}.sta.rpt. Thanks

Have you tried running the assembler?

I agree with Kaz - this appears to be a reporting bug. The timing report has correctly identified one clock. 

 

Given the age of the family you're using I think it's pointless reporting it to Altera. 

 

Cheers, 

Alex

Out of interest, have you tried compiling the design with Max Plus 2? 

A few years ago when I had to modify a 15 year old Flex10k design, I tried porting it to Quartus 9. During the fitter it told me that some Ram configuration was illegal for the Flex, but it compiled without problems in Max Plus2. So I stuck with that.

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
