Mehdi, Mark - not a serious enough issue to create a backward compatibility problem - This requirement was in SystemVerilog 3.0, but got removed by svec - Champions unanimously approved in Oct 25 conference call 52. 1645 SV-BC behavior of keywords directives at end of compilation unit - October 29, 2007 the SV-BC approved, with 3 no votes Cliff, Heath, Stu believe the original restriction is good and that `begin directives should be paired to avoid the potential case where multiple files are compiled in the same compilation unit and somebody forgot to turn off the keywords somewhere in the middle of the list of files. To silently tun off the keywords by reaching an EOF is a bad idea (in Cliff's opinion). An error for a missing `end_keywords directive can be quite useful. - Champions approved in Nov 8 conference call, with 1 abstain (Stu) ######################################################################## From Champions meetings of (December 20, 2007) and (January 17, 2008) ######################################################################## List of Mantis items unanimously approved by both the TCs and the Champions --------------------------------------------------------------------------- (28 mantis items) 1. 2222 SV-BC Completely incorrect statement in 6.5 about variable ports -
