Hi,I'm simulating in Modelsim XAUI Phi core generated by Megawizard for Cyclone V. I use QII 13.0.1. This is a stand-alone simulation (core only) The problems: 1. No stimulus in the simulation files, generated by Megawizard, only "bare" XAUI core called for simulation. 2. When I added stimulus generation module, signal phy_mgmt_waitrequest, set to 1'b0 by reset, set to 1'bZ in every phy_mgmt bus read/write attempt 3. channel 3 of XAUI output becoming undefined soon after simulation started. Anybody have the same problems or may be give any suggestions, advices, solutions??? Thanks.
