Why isn’t  rx_ready asserted for 1G lane after dynamically reconfigured from CPRI 10G to CPRI 1.2G when the firmware in the GTS Dynamic Reconfiguration Controller IP is disabled?

Description

Due to a problem in the Quartus® Prime Pro Edition software version 24.3.1, you may see  rx_ready isn’t asserted at 1G CPRI when the firmware in the GTS Dynamic Reconfiguration Controller IP is disabled while Dynamic Reconfiguration(DR) process from CPRI 10G to CPRI 1.2G.
This is because the firmware in the GTS Dynamic Reconfiguration Controller IP needs to be switched from Enable to Bypass mode.
The software reset controller (SRC) logic was not correctly handling the state transition from Enable to Bypass mode. The state should be driven to ‘0’ when the firmware in the GTS Dynamic Reconfiguration Controller IP is disabled but this was not happening properly.

Resolution

This problem is fixed beginning with the Quartus® Prime Pro Edition software version 25.1.1.
