Claim 4:
5. The server JTAG component adaptive interconnection system according to claim 1, wherein the programmable device is configured to input a serial data code stream to the tested JTAG component through the TDI signal according to a Test Clock (TCK) tick, then receive serial data output through the TDO signal according to the TCK tick, and compare the serial data code stream input through the TDI signal with serial data output through the TDO signal to determine whether the JTAG test chain is normal, and is further configured to, in response to pressure testing being performed on the JTAG test chain, send data code streams at different rates to determine a maximum rate supported by the JTAG interconnection chain.
