Hi,
If you do not understand master HDL.
One of the solution is:
Find documentation for your version of plb_ipif.
Read about IP master interface. Also there you'll
find timing diagram for IP master read/write transaction.
So, your task is, instead of using master HDL, create your own
hdl, which will work according IP master transaction timing diagram.
