+# The following timing values were derived from pages 173-175 of the STM32F429
+# datasheet. Control signals NE1, NL and NWE all have different timing values.
+# Instead of writing individual constraints for every control signal, the most
+# strict constraint is applied to all control signals. This should not cause
+# any P&R issues, since Spartan-6 can handle 90 MHz easily.
+#
+# NOE signal is not constrained, since it drives "T" input of IOBUF primitive.
+#
+# Data and Address buses also have different timings, with Data bus timing being
+# more strict. The same approach is used here, i.e. timing for Data bus is
+# applied to Address bus too.
+#
+# Oh, and stupid datasheet doesn't explicitly specify hold time for the data bus!
