Parse and elaborate rise/fall/decay times
for gates, and handle the rules for partial
lists of times.
Add functions up to elaboration (Ed Carter)
move binary operators to derived classes.
update to match new features.
Handle dumping tasks with no ports.
Add clean target.
quietly ignore specify code.
Handle no ports at all for tasks.
use parent mkinstalldirs.
line comments effects detection of strings etc.
Add support for task output and inout ports.
Elaborate task input ports.
is_constant method for PEConcat.
Document netlist semantics.
Implement the set method.
Add support for CE input to XNF DFF, and do
complete cleanup of replaced design nodes.
xnfsyn generates DFF objects for XNF output, and
properly rewrites the Design netlist in the process.
Add the functor interface for functor transforms.
netlist support for ternary operator.
Get bits of odd sized hex representation.
Better handling of bit width of + operators.
Trim trailing white space from macro values.
simplified process scan for targets.
part select in expressions.
pevent objects have initial values.
set_width for NetESubSignal.
Reduce the excessive line directives from macros.
Handle strings as tokens.
Construct delayed assignment as an equivilent block.
procedural blocking assignment delays.
handle unsupported directives.
