Critical Issue
Description
This problem affects DDR2, DDR3, LPDDR2, RLDRAM II and RLDRAM 3 products.
IP generation fails when you attempt to instantiate your UniPHY-based external memory interface IP with both the Efficiency Monitor and Protocol Checker and Ping Pong PHY enabled.
Resolution
The workaround for this issue is as follows:
- In Qsys, manually instantiate your UniPHY-based external memory interface IP with Ping Pong PHY enabled and the Efficiency Monitor and Protocol Checker disabled.
- Instantiate two copies of the Efficiency Monitor and Protocol Checker and connect them to the avl_c0 and avl_c1 interfaces of the UniPHY IP.
This issue will be fixed in a future version.
