The shift registers are being packed correctly into

both LUTs of the Slices. The real problem is that

the speed files are missing setup/hold times from

the Address to the Clock. Normally there is no

setup time for the Address lines, since they are

considered a data path. In this case, there

should be setup/hold times available.

This issue will be address in a future release.
