+# PDIL-1 stands for Invalid site configuration which according to UG912
+# happens when the route connects to a site pin on a site where the
+# programming of the site is in an invalid state.
+# Since in case of this fuzzer the routing path is random due to
+# non-deterministic choice of source and destination pins
+# we can lower the severity of the PDIL-1 DRC in order to
+# prevent the termination of the execution of the script.
