AR# 42829: MIG 3.8 Spartan-6 MCB - Custom part for MCB allows ranges that exceed supported address space
MIG 3.8 Spartan-6 MCB - Custom part for MCB allows ranges that exceed supported address space
MIG 3.8 and earlier versions allow the user to generate custom memory parts that exceed the address space that is supported by the MCB. The generated controller will have more address pins than are allowed and MAP will generate an error.
The MCB allows a maximum memory density of 4 Gb. The user needs to ensure that the custom memory does not exceed that density. MIG 3.9 release is scheduled to have a check for the maximum allowed memory density.
