Claim 8:
9. A server Joint Test Action Group (JTAG) component adaptive interconnection method, comprising following steps:
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 to form a JTAG test chain; and
connecting JTAG components tested as normal to form a JTAG interconnection chain, wherein a Test Data Output (TDO) signal of a previous JTAG component is connected in series with a Test Data Input (TDI) signal of a next JTAG component in the programmable device, a TDI signal of a first JTAG component is connected with a TDI signal of a JTAG master device, and a TDO signal of a last JTAG component is connected with a TDO signal of the JTAG master device, so as to form the JTAG interconnection chain.
