Jim Lawson 71bcc4c644 Address requested changes - don't require non-$ name.
Suppress warning if name does begin with a `$`.
Fix hierachy tests so they have something to grep.
Announce hierarchy test types.

Jim Lawson 5c4a72c43e Fix normal (non-array) hierarchy -auto-top.
Add simple test.

Jim Lawson 5c504c5ae6 Define basic_cell_type() function and use it to derive the cell type for array references (instead of duplicating the code). 2019-02-15 11:31:37 -08:00
whitequark efa278e232 Fix typographical and grammatical errors and inconsistencies.
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.

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 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)
