General Description: How long can net names and pin names be?
解决方案
Net names can be up to 22 characters long, and pin names can be up to 14 characters long. For buses, this includes the brackets and indices (so BUS[8:0] would be an 8-character name).
Legal Xilinx net/pin name characters are: A-Z, a-z, 0-9, '_', and '-'. Xilinx software is not case-sensitive, so 'Net1' and 'net1' are interpreted as the same net.
