## Rsyn
Rsyn is an open-source C++ framework for physical synthesis (e.g placement, routing, sizing, buffering, restructuring, etc)
research and education. The framework integrates parsers for common academic and industrial formats as Bookshelf, LEF/DEF,
Verilog, Liberty, SDC and SPEF. Benchmarks from several EDA contests from ISPD and ICCAD can be easily loaded.

It also includes standard tools as static timing analysis (STA), routing and congestion estimation.
A built-in graphics user interface (GUI) is also available.


The netlist data model makes use of the new features of C++11. So it becomes very natural and easy to traverse the netlist.
// Traverse pins in reverse topological order.
for (Rsyn::Pin pin : module.allPinsInReverseTopologicalOrder()) {
for (Rsyn::Arc arc : pin.allOutgoingArcs()) { /* … */ }
for (Rsyn::Arc arc : pin.allIncomingArcs()) { /**/ }
Rsyn::Net net = pin.getNet();
if (!net) {
std::cout << “Unconnected pin ‘” + pin.getFullName() + “‘\n”;
} // end if
} // end for
Objects can be extended via attributes, which internally handle modifications in the netlist.
// Creating a new attribute called “visited” to the nets
Rsyn::Attribute<Rsyn::Net, int> attr = design.createAttribute();
for (Rsyn::Net net : module.allNets()) {
attr[net] = computeSomething(net);
} // end for
Rsyn::Net newNet = module.createNet();
attr[newNet] = computeSomething(net);
