An Kintex 7 Ethernet 1000base-x pcs/pma or SGMII ip core was generated and the demo_tb module was created automatically too.It seems that all necessary modules were created too . However when I do the demo simulation,a lot of signals which obviously stand for the received data were in "U" state. and other signals seemed wrong .
I've already updata my ISE to 13.3 edition and Modelsim to 6.6,but nothing changed at all.
the same thing happened when type "do simulate_mit.do" in modulesim and this "do simulate_mit.do" file was given by the ISE too.
ISIM was the same.
I check the signal and found out that the module "GTXE2_CHANNEL_WRAP" did not work correctly,or I should say it didn't work at all.
I want to know that Is there any keypoints need to be paid attention to Kintex7 ethernet IP core simulation or I should do some special setting job when using that module.
So just give me some advises please.
Thank you very much.
