Sir, I would like to design a SFPDP module that receive parallel data from F/o module . This is a part of a recorder. My question is how to proceed with Stratix IV board? Can i use ALTGX Transceiver for that? If so please do mention challenges.

Hi,

Thanks for your update. As I checked with the device datasheet, there should be no issue for the SIV XCVR to support the 625Mbps as the min spec is 600Mbps.

I understand that your latest problem is related to ALTGX and ALT_RECONFIG. To ensure we are on the same page, just would like to check with you on the following:

1. Would you mind to further elaborate on the problem observation ie with some screenshots so that I could have a better understanding.

2. You also mentioned about dynamic reconfiguration in your previous note. Generally it is used only if there is a rate change required. Would you mind to help elaborate on why you need reconfiguratioin and the specific issue that you are observing?

3. Just would like to check with you if you are currently observing issue in simulation or hardware? If it is hardware, I would recommend you to start by running Modelsim simulation to isolate out any functional issue before proceed to hardware testing.

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin
