Stratix10 GX : Error (170012): Issue with fitter and number of LABs ineferred

Hello Forum, 

 

What we are doing

-------------------

While fitting our logic, we are getting this error -

Error (170012): Fitter requires 108583 LABs to implement the design, but the device contains only 93312 LABs

 

QUESTION:

--------------------

 

Not able to corelate to why and where is it mentioned that 1SG280HU2F50E2VG  device has93312 LABs  and constitution of LABs and is it the issue with number of DSP blocks (100%), or what needs to be done in re-design in order to solve this fitter issue.

Any clue will be appreciated !!! OPTIMISATION is done for AREA. 

Below is the fitter summary

Hi Swapnil,


I suggest you to experiment with tool constraint for compiler setting. Quartus offer different setting for area routability and optimization.


Thanks,

Regards
