+Known Issues & Limitations
+==========================
+
+Not all SystemRDL features are supported by this exporter. For a listing of
+supported properties, see the appropriate property listing page in the following
+sections.
+
+
+External Components
+-------------------
+Regfiles, registers & fields instantiated using the ``external`` keyword are not supported yet.
+
+
+Alias Registers
+---------------
+Registers instantiated using the ``alias`` keyword are not supported yet.
+
+
+Unaligned Registers
+-------------------
+All address offsets & strides shall be a multiple of the regwidth used. Specifically:
+
+* Each register's address and array stride shall be aligned to it's regwidth.
+* Each regfile or addrmap shall use an offset and stride that is a multiple of the largest regwidth it encloses.
+
+
+No partial writes
+-----------------
+
+Some protocols describe byte-level write strobes. These are not supported yet.
+All write transfers must access the entire register width.
