Are you trying to set the TX VOD of a Cyclone V device statically? You can set this in the Quartus II Assignment Editor or Pin Planner ( Refer to chapter 19 of the Altera Transceiver PHY IP Core User Guide) https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/ug/xcvr_user_guide.pdf The 'Analog Settings for Cyclone V Devices' section of chapter 19 explains how to set it on page 19-33 For a translation of the TX VOD settings to the actual mV, refer to the Cyclone V Device Datasheet : https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/cyclone-v/cv_51002.pdf ( Table 21 shows the list of Vod values based on a TX termination resistance value of 100 ohms) For additional clarification, please file a Service Request with Altera Hope this helps Regards, Mahathi
