LogiCORE VLYNQ v1.2 - Why does the OPB clock fail to restart after it has been stopped?

Description

Why does the OPB clock fail to restart after it has been stopped?

Solution

The feature to stop the OPB clock to save power is not supported, and there are no current plans to add this feature to the Xilinx LogiCORE VLYNQ bus interface. 

 

Attempting to stop the OPB clock might cause the LogiCORE VLYNQ core to lock up, which could potentially lock up any devices connected to the VLYNQ bus interface. 

 

See (Xilinx Answer 23509) for a detailed list of LogiCORE VLYNQ Release Notes and Known Issues.
