Routing Architecture
^^^^^^^^^^^^^^^^^^^^
The routing architecture shares the same principle as the SOFA HD routing architecture (See details in :ref:`sofa_hd_fpga_arch_routing_arch`).
.. note:: Different from SOFA HD, each routing channel consists of 60 routing tracks. See details in :numref:`table_qlsofa_hd_fpga_arch_routing_track_distribution`.
