Claim 12:
13. The server JTAG component adaptive interconnection method according to claim 9, wherein the step of by a programmable device, simulating JTAG timing according to a JTAG protocol and testing JTAG channels of JTAG components connected to the programmable device one by one comprises:
by the programmable device, simulating the JTAG timing, switching a JTAG Test Access Port (TAP) state machine of each JTAG component connected to the programmable device to a shift Instruction Register (shift-IR) state one by one, and inputting a BYPASS instruction to the corresponding JTAG component, whereby a shortest serial path is formed between a TDI and a TDO of each JTAG component; and
by the programmable device, simulating the JTAG timing, switching the JTAG TAP state machine of the corresponding JTAG component to a shift data register (shift-DR) state, and sending out a TDI signal of the corresponding JTAG component from the TDO signal after a Test Clock (TCK) tick to form the JTAG test chain.
