Maciej Suminski fc0728ab6f vhdlpp: Forward typedefs.
It was required to make it possible to use typedefs in port types.
Types from packages are emitted in `ifdef..`endif instead of package..endpackage.

The purest solution is to keep package..endpackage and emit appropriate prefix.
Also, it would be great to have constants emitted in the same way.

Cary R 2e8c4e3dbc Basic patch from github #44 2014-11-04 11:39:01 -08:00
Maciej Suminski c55a013162 vhdlpp: Support for integer() function.
Note: I could not find any info about the integer() function, but it is
used in the VHDL standard packages (e.g. math_real, see:
http://www.csee.umbc.edu/portal/help/VHDL/packages/mathpack.vhd)
Real numbers are rounded, this is compatible with ModelSim behavior.

Maciej Suminski 675b7d8efa vhdlpp: Support for std_logic_vector return type in functions.
VHDL does not allow to specify the size of returned std_logic_vector,
whereas Verilog requires the size to be known in advance. The size of
the vector is determined by checking the type of expression used in the
return statement.
