How to adjust data rate in the transceiver tool kit?

Hi,

I am using Transceiver Signal Integrity Development Kit (Stratix V GX) to test the BER of 4 transmission channels. I used the transceiver Toolkit Designs sample for QII R14.0 (7 channels, 11.3gbps (http://www.alterawiki.com/uploads/7/75/sv_7ch_11p3gbps.qar)) from http://www.alterawiki.com/wiki/transceiver_toolkit.

My question is: I wish to test different channel data rates at 600Mbps, 1.25Gpbs, 2.5Gpbs, 5Gpbs, 8Gpbs and 10Gpbs, but the data rate of the sample was fixed at 11.3Gpbs. Can anyone tell me how to change the data rate settings?

Thank you

Adam

    If I'm not mistaken, the design uses Qsys, so you change the data rate setting in Qsys. To do that, open .qsys file with Quartus II software, find Custom PHY or Native PHY in the Qsys system, and edit the PHY parameters.
