12 years agoThank you very much for kind answer.
However, I think I correctly specified the I/O standards by setting them to 1.5-V PCML. And they are all paired in p and n as shown in Pin Planner. I simply connected all hsma_rx_p pins to the DATAIN and hsma_tx_p to DATAOUT. According to the error messages, hsma_tx_p doesn't seem to have a problem, but only rx does.
