| FPGA Architecture Description |
| ============================= |
| |
| VTR uses an XML-based architecture description language to describe the targeted FPGA architecture. |
| This flexible description langauge allows the user to describe a large number of hypothetical and commercial-like FPGA architectures. |
| |
| See the :ref:`arch_tutorial` for an introduction to the architecture description langauge. |
| For a detailed reference on the supported options see the :ref:`arch_reference`. |
