How to disable multiple reconfiguration profile when I only use one of them?

Hi, I'm using 1G/2.5G/5G/10G Multi-rate Ethernet PHY Intel® Stratix® 10 FPGA IP to implement 1G Ethernet. I choose the external PHY to MGBASE-T, and the PHY speed is 1G/2.5G. There are two reconfig...

Hi Rain Bow,


To change the PHY speed, kindly use the reconfiguration block in the MAC+PHY example design.

For more detailed steps, refer to Multi rate Ethernet UG page 21 4.3. Switching Operation Speed :

https://www.intel.com/content/www/us/en/products/details/fpga/intellectual-property/interface-protocols/10g-multirate-ethernet-phy.html


When you configure the PHY in 1G/2.5G configuration, Intel recommends that you add the following constraint in the timing constraint file. Kindly refer to page 20 for the Timing Constraint.


Regards,

Pavee

Hi,

I'm not trying to know how to switch speed, I only want to know how to disable Quartas analyze timing for 2.5G speed, 1G is enough for my design.

Thanks.
