Machine learning and cloud computing techniques can help accelerate timing closure for FPGA designs without any modification to original RTL code. RTL is generally frozen closer to system delivery target to avoid injecting new unforeseen bugs or significantly affecting design characteristics. In these circumstances, developers trying to close timing are(More)
FPGA CAD tool parameters controlling synthesis optimizations, place and route effort, mapping criteria along with user-supplied physical constraints can affect timing results of the circuit by as much as 70% without any change in original source code. A correct selection of these parameters across a diverse set of benchmarks with varying characteristics and(More)
We can use Cloud Computing and Machine Learning to help deliver timing closure of FPGA designs using InTime [2], [3]. This approach requires no modification to the input RTL and relies exclusively on manipulating the CAD tool parameters that drive the optimization heuristics. By running multiple combinations of the parameters in parallel, we learn from(More)
We can achieve reliable timing closure of FPGA designs using machine learning heuristics to generate input parameter settings for FPGA CAD tools. This is enabled by running multiple instances of CAD tool with different sets of these input parameters and logging of resulting timing slack values into a database. We incrementally build this database and run(More)
Machine Learning approaches for automated selection of FPGA CAD tool parameters have been demonstrated to be useful for timing closure of FPGA designs [3], [4]. This is achieved by running the CAD tool multiple times with small variations in the the CAD parameter values. The timing slack from each run is recorded into a database along with all input(More)
