Abstract

We present a post-routing model that relates both logic and routing architecture parameters to wirelength for a homogeneous FPGA architecture. Our model relies on Rent's parameter generated from the pre-technology mapped netlist rather than post-placement netlist making it independent from optimization goal of the technology-mapping, clustering and placement stages of the FPGA CAD flow. We achieve an average mean absolute percentage error (MAPE) of 36% relative to the Verilog-to-Routing (VTR) based wire-length analysis using MCNC and VTR benchmarks, while state-of-the-art approach achieves a MAPE of 57%. This work forms the basis for implementing post-routing delay, routability and power models, since each can be expressed as a function of net length.
