Does anyone have an example .ucf they can send me for two TEMACs (both hard) using SGMII? I have 4 ethernet ports, but am only able to get one port working at a time. I read the interupt register in the TEMACs and found that only one port is completing auto-negotiation (the one that works). Therefore, I am assuming that it is in my constraints somewhere and would like to double check. I have ruled out board issues by creating a custom build that swaps TEMACs and I am able to communicate on a different port then, but not the original.
