+# Waive the always-comb rule in the various "pgd" modules. The rule is checking
+# that we don't use always @*, and suggests we use always_comb instead.
+# Unfortunately, the code in question doesn't really translate to always_comb.
+# And we don't really care about the linting rule: the code is just supposed to
+# be a behavioural model of some analog code that isn't really part of the OT
+# open-source repo. Waive the warning.
