Claim 19:
20. The non-transitory computer-readable storage medium according to claim 15, wherein the computer program, upon execution by the processor, is further configured to cause the processor to:
simulate the JTAG timing, switch 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 input a BYPASS instruction to the corresponding JTAG component, whereby a shortest serial path is formed between the TDI signal and the TDO signal of each JTAG component; and
simulate the JTAG timing, switch the JTAG TAP state machine of the corresponding JTAG component to a shift data register (shift-DR) state, and send 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.
