Virtex-4 RocketIO - What are the wait cycles before DRDY is asserted in dynamic reconfiguration for the MGT?

説明

NOTE: This Answer Record is specifically for the MGT. 

In the Virtex-4 FPGA Configuration User Guide v1.1 (Xilinx UG071), Chapter 6, Reconfiguration Techniques, Figures 6-4 and 6-5 on page 81 show an undetermined number of wait cycles from when DEN is asserted to when DRDY is asserted.

For the MGT, the number of wait cycles after DEN is three (3) before DRDY is asserted.
