adding 2 high speed reed solomon decoders increased the 'Logic Utilization' in 20% (only 7% was expected based on other project where i also added the same 2 high speed reed solomon decoders).

Hi,

Thanks for your update. For your information, after design compilation, you can check the resource utilization by the HS RS decoder instance at Fitter -> Resource Section -> Resource Utilization by Entity. You may then cross check the resource utilization between your two design to see if there is any anomaly.

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin
