Traces of differential signals pairs are :
For applications where traces length has to be matched or timing differences have to be compensated, Table 42 and Table 43 list the trace length of I/O signal lines measured from FPGA balls to B2B connector pins.
Pairs of pins that form a differential I/O pair appear colored together in the table. An electronic version of these pin-out tables are available for download from the Trenz Electronic support area of the web site.
