8.5.9. Using the JTAG Debug Service

The JTAG Debug service allows you to check the state of clocks and resets within your design.

The following is a JTAG Debug design flow example.

  1. To identify available JTAG Debug paths:
    get_service_paths jtag_debug
  2. To select a JTAG Debug path:
    set jtag_debug_path [lindex [get_service_paths jtag_debug] 0]
  3. To claim a JTAG Debug service path:
     set claim_jtag_path [claim_service jtag_debug$jtag_debug_path mylib]
  4. Running the JTAG Debug service:
    jtag_debug_reset_system $claim_jtag_path
    jtag_debug_loop $claim_jtag_path [list 1 2 3 4 5]
