 Spypads are physical output pins on a FPGA chip through which you can read out internal signals when doing silicon-level debugging. The XML syntax for spypads and other 
 global signals can be found on our :ref:`circuit_library` documentation page.

-In this architecture file, the output ports of a 6-input Look Up Table (LUT) are defined as spypads using the XML syntax ``is_global`` and ``is_io``. As a result, all of the outputs from the 6-input LUT will be visible in the top-level module. The output ports to the 6-input LUT are declared from **LINE181** to **LINE183** and belong to the ``frac_lut6_spypad`` ``circuit_model`` that begins at **LINE172**.
