Arria II rx_signaldetect

Question

Hello,

I am using the Arria II demo board (125 version) and have ALTGX configured in basic mode. I turned on 8B/10B to enable the rx_signaldetect output. The rx_signaldetect is stuck high all the time no matter what I do. I followed the couple of reset sequences suggested on the Altera site and looked at the recommendations on the Stratix IV manual with no success.

I have tried with a signal present, without a signal preset, with the loop back board on the HSMC connector, with our own HSMC board, again with no success.

I tried with manual LTR/LTD and automatic mode.

Did anyone run into this or similar issue?

Thank you!

Dino,  Thank you for the reply!  It would be nice if the links to the updates worked! :)  I have to move on to a different project.  When/if I come back to this, I will deal with it then.

I checked the link again today and there was an update to the solution related to a bug in 11.0.  I applied the suggestion and now it works.
