calculation of Cyclone's Regsisters and LUTs

Dear All, 

 

I was updating the resources for devices in Cyclone family ( IOs, LUTs, Registers ... etc. 

 

I was running the Quartus 11.1 release on specific device (e.g. EP1C3T100C6). Analyze the "<TopDesign.fit.summry>" and "<TopDesign>.fit.rpt" files to extract all the available resources. 

 

Would you please advise me, how can i get/extract the available Registers and LUTs values for any device such as (EP1C3T100C6) from any of the above files ? 

 

 

If this is not the professional or the right way to get these resources, then what should i do ? 

 

 

p.s. registers should be different than luts. 

 

Example for what i am doing to extract the Memory Bits from the "<TopDesign.fit.summry>" . From the following line exist in this file, I parse it and update my memory bits value with 59,904 

 

 

Total memory bits : 0 / 59,904 ( 0 % ) 

 

Thanks in Advance. 

 

Best Regards, 

Islam

memory bits describe how many bits will be used in the Block RAM. the fitter report should be pretty clear about how many registers are used, see attached

hi thepancake, 

 

Thanks a lot for your reply. I saw the screen shot. I believe that the registers can be calculated from the line of "dedicated logic register" with the value 99,280. But, the point is, i can't find such field in any file came out from the fitter of Quartus for the cyclone family. 

 

So, would you please run the quartus on Cyclone family and see if i can get the "dedicated logic registers" from any of the reports generated ? 

 

 

Thanks in advance.
