Description
The LED_LINK signal can be different from the value of the LINK_STATUS register in TSE IP MegaCore® function in Quartus® II software version 13.0.
This is due to the fact that the register will latch a value of 1'b0 to ensure the software knows that the link was lost. Once read the LINK_STATUS register will update to the current link status.
Please refer to the TSE user guide for the behavior description of LINK_STATUS.
