| | | | | | | | | - 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)

| * Minor revision to -expose in setundef passAman Goel2018-09-101-1/+7
| | | | | | | | Adds default value option as -undef when -expose used. Not having set the value mode set can cause the setundef pass to abort.

| | * Consistent use of 'override' for virtual methods in derived classes.Henner Zeller2018-07-20120-265/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PR prints the name of the module when displaying the final area count. Pros: - Easier for the user to `grep` for area information about a specific module Cons: - Arguably more verbose, less "pretty" than author desires Verification: ~~~~ 30c30 < Chip area for this module: 20616.349000 --- > Chip area for module '$paramod$d1738fc0bb353d517bc2caf8fef2abb20bced034\picorv32': 20616.349000 70c70 < Chip area for this module: 88.697700 --- > Chip area for module '\picorv32_axi_adapter': 88.697700 102c102 < Chip area for this module: 20705.046700 --- > Chip area for top module '\picorv32_axi': 20705.046700 ~~~~
