FPGA CAD Tools
- The latest version of VPR , a placement and routing tool for FPGA research, is available from as part of the VTR (Verilog to Routing) source archive.
- VPR and T-VPack version 4.30; this is the version used in Architecture and CAD for Deep-Submicron FPGAs.
New! New version of COFFE
COFFE is a CAD tool that can automatically optimize low-level FPGA circuitry, including the full custom circuitry of logic blocks and routing, the semi-analog circuitry of block RAMs, and the standard cell circuitry of heterogeneous blocks (e.g. DSP blocks).
It produces area and delay estimates that can be fed into VPR for architecture exploration. COFFE uses enhanced area and delay modeling vs. prior approaches, and VPR (post 7.0) has been upgraded to also use these enhanced models to be compatible with COFFE.

VPR is part of the
suite of computer benchmarks
(the standard benchmarks used to determine the speed of various workstations).
I have found it to be a good predictor of the speed of commercial FPGA CAD tools on various computer hardware as well. Results are
