I don't have a good story for that one because that is the open core plus logic. Open up Timequest and have it report the worst failing paths. Then copy and paste those paths into a text file and either attach it to this thread or send it to me in a private message and I'll take a look. This logic is used to hold your logic in reset after a timeout if you disconnect the programming cable and use an IP core in OCP mode.
