Running the Titan Benchmarks

This tutorial describes how to run the :ref:`Titan benchmarks <titan_benchmarks>` with VTR.

Integrating the Titan benchmarks into VTR

The Titan benchmarks take up a large amount of disk space and are not distributed directly with VTR.

The Titan benchmarks can be automatically integrated into the VTR source tree by running the following from the root of the VTR source tree:

$ make get_titan_benchmarks

which downloads and extracts the benchmarks into the VTR source tree:

Done
Titan architectures: vtr_flow/arch/titan
Titan benchmarks: vtr_flow/benchmarks/titan_blif

Once completed all the Titan benchmark BLIF netlists can be found under $VTR_ROOT/vtr_flow/benchmarks/titan_blif, and the Titan architectures under $VTR_ROOT/vtr_flow/arch/titan.

Note

:term:`$VTR_ROOT` corresponds to the root of the VTR source tree.

Running benchmarks manually

Once the benchmarks have been integrated into VTR they can be run manually.

For example, the follow uses :ref:`VPR` to implement the neuron benchmark onto the startixiv_arch.timing.xml architecture at a :option:`channel width <vpr --route_chan_width>` of 300 tracks:

$ vpr $VTR_ROOT/vtr_flow/arch/titan/stratixiv_arch.timing.xml $VTR_ROOT/vtr_flow/benchmarks/titan_blif/neuron_stratixiv_arch_timing.blif --route_chan_width 300
