Simulating with the NCSim Software


The DDR and DDR2 SDRAM High-Performance Controller MegaCore functions do not fully support the NCSim software.

This issue affects all configurations.

The design does not simulate.


Set the –relax switch for all calls to the VHDL analyzer.

�This issue will be fixed in a future version of the DDR and DDR2 SDRAM Controllers with ALTMEMPHY IP.
