Abstract

Physical synthesis for a circuit design can include determining (320), using a processor, features relating to a signal path of the circuit design not meeting a timing requirement, processing (330) the features through a first neural network model using the processor, wherein the first neural network model is trained to indicate effectiveness of a first physical synthesis optimization, and selectively performing (335, 340), using the processor, the first physical synthesis optimization for the signal path based upon a result from the first neural network model.

Description

Technical field [0001] The present invention relates to integrated circuits (ICs), and more specifically, to physical synthesis for adapting circuit designs implemented within ICs. Background technique [0002] An integrated circuit (IC) can be implemented to perform various functions. Some ICs can be programmed to perform specified functions. An example of a programmable IC is a field programmable gate array (FPGA). FPGAs usually include an array of programmable cells. These programmable patches can include, for example, input / output modules (IOB), configurable logic modules (CLB), dedicated random access memory modules (BRAM), multipliers, digital signal processing modules (DSP), processing Controller, clock manager, delay locked loop (DLL), etc. [0003] Each programmable unit usually includes a programmable interconnect circuit and a programmable logic circuit. Programmable interconnect circuits generally include a large number of interconnect lines of different lengths in...
