Ruben Undheim 436e3c0a7c Refactor code to avoid code duplication + added comments 2018-10-20 16:06:48 +02:00
Ruben Undheim 397dfccb30 Support for SystemVerilog interfaces as a port in the top level module + test case 2018-10-20 11:58:25 +02:00
Ruben Undheim c50afc4246 Documentation improvements etc. 
- Mention new feature in the SystemVerilog section in the README file
- Commented changes much better
- Rename a few signals to make it clearer
- Prevent warning for unused signals in an easier way
- Add myself as copyright holder to 2 files
- Fix one potential memory leak (delete 'wire' if not in modport)

Ruben Undheim 458a94059e Support for 'modports' for System Verilog interfaces 2018-10-12 21:11:48 +02:00
Ruben Undheim 75009ada3c Synthesis support for SystemVerilog interfaces

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
