Hello,

I think you are profession in my issues, I need your help.

I have some troubles with my design with Stratix II Devices. I use MegaWizard, Quartus's Web edition, to create ALTMEMPHY. It releases many files such as:

*_alt_mem_phy_reconfig_sii

*_alt_mem_phy_ sii

alt_mem_phy_defines

alt_mem_phy_sequencer.vhd

*_altmem_phy_sequencer_wrapper.vo

...

Module "alt_mem_phy_sequencer.vhd" is encrypted, so I can't see anything. How can I use this module?

To ensure my logic is ok, I simulate them with my logic by using NCverilog 5.5. But the way ALTMEMPHY tool uses parameter is new to me. And when I run my simulation, it can not stop and print out may warnings. So you can give me your advice.

I'm very impressed by ALTMEMPHY but I can't use it for a long time.

Thank you in advance!
