Release 2.6.2 2025/03/30
|
|
------------------------
|
|
|
|
The following functions have been renamed to to_string and return std::string
|
|
instead of "const char*"
|
|
|
|
Vertex::name
|
|
FuncExpr::asString
|
|
TimingRole::name
|
|
MinMax::asString
|
|
MinMaxAll::asString
|
|
RiseFall::asString
|
|
RiseFallBoth::asString
|
|
Transition::asString
|
|
Tag::asString
|
|
timingSenseString
|
|
|
|
The following classes now return const objects.
|
|
|
|
MinMax
|
|
MinMaxAll
|
|
RiseFall
|
|
RiseFallBoth
|
|
Transition
|
|
TimingRole
|
|
|
|
Release 2.6.1 2025/03/??
|
|
-------------------------
|
|
|
|
The following classes have been replaced by the class Path.
|
|
PathEnumed
|
|
PathPrev
|
|
PathRef
|
|
PathVertex
|
|
PathVertexPtr
|
|
PathVertexRep
|
|
|
|
The PathExpanded::prevArc function has been removed. Use Path::prevArc instead.
|
|
|
|
Release 2.4.0 2023/01/19
|
|
-------------------------
|
|
|
|
The Network API and associated containers now 'const' the network class objects.
|
|
The Network API now requires network objects to have and "id" function that
|
|
returns an ObjectId (unsigned int) that is unique to the object among objects
|
|
of the same type.
|
|
|
|
virtual ObjectId id(const Instance *instance) const = 0;
|
|
|
|
Object IDs are used for comparing and hashing network objects.
|
|
If network Ids are not available in the host application database object pointers
|
|
can be cast to intptr_t. Using pointers as object Ids can result in memory layout
|
|
dependent results that are inconsistent from run to run or across host systems.
|
|
|
|
Many Network and Sta class functions now return collections rather than pointers
|
|
to temporary collections that the caller would have to delete.
|
|
|
|
Release 2.3.1 2022/06/12
|
|
-------------------------
|
|
LibertyCellTimingArcSetIterator has been removed.
|
|
Use range iteration as shown below:
|
|
for (TimingArcSet *arc_set : cell->timingArcSets())
|
|
for (TimingArcSet *arc_set : cell->timingArcSets(from, to))
|
|
|
|
TimingArcSetArcIterator has been removed.
|
|
Use range iteration as shown below:
|
|
for (TimingArc *arc : arc_set->arcs())
|
|
|
|
LibertyCellSequentialIterator has been removed.
|
|
for (Sequential *seq : cell->sequentials())
|
|
|
|
Release 2.1.1 2020/12/13
|
|
-------------------------
|
|
Report::error, Report::warn functions now take a unique message ID as a first argument.
|
|
InternalError has been renamed Report::cricical.
|
|
|
|
Release 2.1.0 2020/04/05
|
|
-------------------------
|
|
All public headers files have been moved to include/sta.
|
|
|
|
The following iterators have been removed.
|
|
Use range iteration on the returned collection shown next to them instead.
|
|
LibertyCellInternalPowerIterator cell->internalPowers()
|
|
LibertyCellLeakagePowerIterator cell->leakagePowers()
|
|
|
|
Release 2.0.18 2020/02/15
|
|
-------------------------
|
|
|
|
The following iterator functions are deprecated:
|
|
|
|
TimingArcSet::timingArcIterator()
|
|
Sdc::clockIterator()
|
|
|
|
Use the iterator class constructor instead. This avoids new/deletes of
|
|
the iterators by stack allocating them. For example,
|
|
Instead of
|
|
|
|
TimingArcSetArcIterator *arc_iter = arc_set->timingArcIterator();
|
|
while (arc_iter->hasNext()) {
|
|
TimingArc *arc = arc_iter->next();
|
|
}
|
|
delete arc_iter;
|
|
|
|
use the following:
|
|
|
|
TimingArcSetArcIterator arc_iter(arc_set);
|
|
while (arc_iter.hasNext()) {
|
|
TimingArc *arc = arc_iter.next();
|
|
}
|
|
|
|
StaException renamed to Exception
|
|
|
|
Release 2.0.17 2019/11/11
|
|
-------------------------
|
|
|
|
Network::setVertexIndex renamed to setVertexId
|
|
Network::vertexIndex renamed to vertexId
|
|
|
|
TransRiseFall renamed to RiseFall
|
|
TransRiseFallBoth renamed to RiseFallBoth
|
|
|
|
Release 2.0.0 2018/06/11
|
|
-------------------------
|
|
|
|
