Disclosed are methods and systems for characterizing and analyzing an electronic system design including a parallel interface. Some methods and systems identify an electronic design including a parallel interface, determine a single circuit representation including the parallel interface from the electronic design, and analyze the parallel interface to determine waveform responses of the parallel interface by using channel analysis techniques without performing circuit simulations. Some other methods and systems are directed at performing channel analyses for a communication interface of an electronic system by concurrently applying stimuli to corresponding transmitters of a communication interface, characterizing the communication interface to perform a single simulation on the communication interface with the stimulus to determine responses at receivers of the communication interface, and determining waveform responses of the communication interface by performing operations on the responses and an input signal to the communication interface.

Method, system, and computer program product for performing channel analyses for an electronic circuit design including a parallel interface

The present disclosure relates to a system and method for algorithmic modeling interface ('AMI') model development. Embodiments may include enabling a selection from a plurality of templates associated with an advanced equalization algorithm at a graphical user interface. Embodiments may further include receiving a selection of at least one of the plurality of templates at the graphical user interface and displaying a selected template at the graphical user interface. Embodiments may also include allowing a user to edit one or more parameters associated with the selected template at the graphical user interface and generating an algorithmic modeling interface ('AMI') model based upon, at least in part, the selected template and the one or more parameters.

Algorithmic modeling interface process

The present disclosure relates to a system and method for simulating channels in an electronic circuit design. Embodiments may include receiving, at one or more computing devices, an electronic circuit design including at least one channel. Embodiments may further include transmitting two or more inputs from two or more transmitter drivers on two or more wires to the at least one channel. In some embodiments, the inputs may be distributed across the wires based upon a chordal code. Embodiments may also include generating simulated waveforms based upon the inputs. Embodiments may further include transmitting the simulated waveforms from the channel on the wires to a comparator block. Embodiments may also include comparing the simulated waveforms on the wires at the comparator block to produce two or more simulated outputs. Embodiments may include transmitting the simulated outputs from the comparator block on the wires to two or more post-comparator receivers.
