FPGA Architecture Description

VTR uses an XML-based architecture description language to describe the targeted FPGA architecture. This flexible description language allows the user to describe a large number of hypothetical and commercial-like FPGA architectures.

See the Architecture Modeling for an introduction to the architecture description language. For a detailed reference on the supported options see the Architecture Reference.
