This is a core file that defines the major data types used by VPR.
This file is divided into generally 4 major sections:
- Global data types and constants
- Packing specific data types
- Placement specific data types
- Routing specific data types
Key background file:
An understanding of libarchfpga/physical_types.h is crucial to understanding this file. physical_types.h contains information about the architecture described in the architecture description language
Key data structures: t_rr_node - The basic building block of the interconnect in the FPGA architecture
Cluster-specific main data structure: t_pb: Stores the mapping between the user netlist and the logic blocks on the FPGA architecture. For example, if a user design has 10 clusters of 5 LUTs each, you will have 10 t_pb instances of type cluster and within each of those clusters another 5 t_pb instances of type LUT. The t_pb hierarchy follows what is described by t_pb_graph_node
