Maciej Suminski acb4ca8e47 vhdlpp: More descriptive error message for a missing function. 2016-01-05 13:55:22 +01:00
Maciej Suminski ba3c07a59a vhdlpp: CHARACTER type is converted to bit[7:0] instead of byte.
This way it is possible to have limited size strings. Previously they
were translated to unpacked array of bytes, which cannot be assigned as
it was a string.

Maciej Suminski afaedbd06d vhdlpp: Corrected to_integer() & resize() functions.
to_integer() handles sign and resize() really applies size casting.

Maciej Suminski 25c3798248 vhdlpp: Elaborate and emit functions work with ScopeBase instead of Architecture. 2015-02-04 16:57:43 +01:00
Maciej Suminski d4dd635bf6 vhdlpp: Added ExpNew class. 2015-02-04 16:57:43 +01:00
Maciej Suminski 9b3bd039bb vhdlpp: Added ExpCast class. 2015-02-04 16:57:42 +01:00
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 97df6183a9 vhdlpp: Emit '-' std_logic value as 'x'.
Note: It is not a direct ("don't care" vs "unknown"), but I could not
find anything that suits better.

Maciej Suminski 5ed60a151f Added support for real type in vhdlpp. 2014-08-06 15:00:35 +02:00
Larry Doolittle be17bfc0e9 Spelling fixes
Mostly comments.
One user-visible string ("Evalutated to ") changed in the debug_eval_tree case.

Stephen Williams d630e4dfe9 Elaborate VHDL entity port types/expressions.
We need to elaborate expressions so that function calls in
expressions (i.e. ranges) get bound to their proper scope.
This binding is in turn used to emit package scopes. This
is particularly interesting for ports of entities.

Stephen Williams 0fcd2d9db6 Handle rising_edge and falling_edge functions. 2013-06-12 14:21:35 -07:00
Stephen Williams bc77a19059 Use $ivl_unsigned to implement VHDL to_unsigned function.
The VHDL to_unsigned function with to arguments is best handled
in the ivl elaborator, so have it generate an $ivlh_to_unsigned
function call in the vhdlpp code, and implement it in the ivl
core.

Also, implement the 'length attribute as a $bits() call for
similar reasons.

Stephen Williams 6394a4d78d Rework scope types and constants so we can tell imported from local names.
The package emit of types and constants needs to know which names are
from the current type and which are imported from libraries. Rework
the scope handling of those names so that the information is preserved.
