Description

Keywords: OPB IPIF V3_01_A, opb ipif, opb_ipif, Sln_xferAck

The Sln_xferAck output is not registered in version V3_01_A of the OPB IPIF. This causes long timing paths when it is used with MicroBlaze, which makes it difficult to meet a 100 MHz requirement.

Solution

This problem has been fixed in the latest EDK 8.1i Service Pack, available at:

The first service pack containing the fix is EDK 8.1i Service Pack 1.
