The BUFG cell is a global buffer which distributes high-fanout clock signals throughout the device. For an XC4000 design, you can use a maximum of eight BUFG symbols (assuming that no specific BUFGP or BUFGS buffers are specified). The BUFG is converted to a BUFGP or BUFGS for the XC4000 architecture. For the Virtex family, you can use a maximum of four BUFG symbols in Virtex and eight BUFG symbols in Virtex-E designs. The BUFGE is a global buffer that uses the 'early' routes on the device. The BUFGLS cell is a global buffer cell which distributes high-fanout signals throughout the device. The BUFGLS uses low-skew modes on the I/O buffers. The BUFGP is a primary global buffer. The BUFGS is a secondary global buffer. Both cells can drive any of four global vertical routes per column of CLBs. Each one of the four global vertical lines can drive the CLB clock (K) pin directly, and a small subset of the other CLB pins, depending on the type of buffer and the position (refer to the library guide).
