Critical Issue
Description
If you run an abstract PHY simulation with a reset duration of less than 100ns on
global_reset_n, the simulation may hang and fail to complete. This
problem is independant of the targeted external memory protocol, the particular IP
configuration, or the simulator in use.
Resolution
The workaround for this problem is to reduce the reset duration to less than 100ns.
This problem is fixed in version 15.1.1.
