Good day!
In fitter I have some identical errors:
Error: Cannot place pin Ddr2SdramDq[28] to location AN17
Error: Can't place VREF pin AR16 (VREFGROUP_B7_N1) for pin
Ddr2SdramDq[28] of type bi-directional with SSTL-18 Class II I/O
standard at location AN17
Error: Too many output and bidirectional pins in I/O bank 7 assigned
near VREF pin AR16 (VREFGROUP_B7_N1) on device EP2SGX90FF1508C3 -- no
more than 20 output and bidirectional pins allowed near the VREF pin
when voltage referenced pins are driving in, but there are potentially
21 pins driving out
Help!!!
