I have a similar problem, but I don't read at all. I only use the component to write to the configuration memory.
I have tried to set rden=1 (which feels strange when you don't want to read), but the component is optimized away anyway.
Is there any specific operation I need to perform to get it to stay in my design?
I tried to forward some of the address lines to a debug pin or use signal tap, in this case the component stays and work, but I don't want this code in my final product.
Thanks / Joakim

If your application code never reads the EEPROM then I'm assuming the data you are writing is new configuration bitstream, for use when the device is reconfigured, i.e. a sort of bootloader?
In that case I would try adding a synthesis keep or preserve attribute to the signals mapped to the ASMI instance.
For a bootloader, especially one to be used by the end customer, I would always read back and verify the EEPROM data anyway.
