I am wondering, if I could utilize the chips' internal ufm and get over the Initialization problem??

Another option, which I thought of was, using the 'on chip memory' IP. However it requires using the Avalon-MM interface and will require making major changes in the design and doing verification again...

My current design is just using a single port ROM, (which I think gets implemented using the M9K blocks).

So do I have any options available?? I checked for 10M04 devices, (as this problem seems to occur only with the smallest 10M02 device), but 10M04 are all out of stock, everywhere I checked..

So I am really stuck with using much bigger and expensive 10M08 device, or figure out how to use Avalon-mm in my design, then re-do the design and verification effort...
