Abstract
A system and method transforms a model of electronic circuit to improve emulation speed and/or reduce emulation area. The model may be divided into partitions; a sequence of storage elements may be created on a partition boundary to allow a partition to process the contents of the storage elements. The disposition of the sequence may correspond to a connection between hardware emulation elements to compensate for latencies therebetween.

A computer-implemented method comprising:
- receiving first data representing a hardware-description language (HDL) description of an electronic circuit;
- identifying, using the first data, a first description of a first storage element configured to process, during a first time period, an input signal to store data associated with the input signal and to output, during a second time period, an output signal representing the data;
- determining a memory structure configured to store the data;
- determining a second description of a second storage element configured to store a reference value indicating a location of the data in the computer-memory structure, a topology of the second storage element corresponding to a topology of the first storage element;
- determining, using the first data and the second description, a circuit model corresponding to the HDL description and the second storage element;
- storing, using a first portion of the circuit model corresponding to the second storage element, the reference value;
- and
- processing, by the memory structure during the second time period, the reference value to output the data.

A computer-implemented method for modeling circuit behavior, the method comprising:
- receiving first data representing a hardware-description language (HDL) description of a first electronic circuit;
- identifying in the first data, a first representation of a first group of circuit elements corresponding to a circuit-element transformation technique;
- determining a second representation of a second group of circuit elements by applying the circuit-element transformation technique to the first group of circuit elements;
- identifying a second electronic circuit determined by replacing the first group of circuit elements in the first data with the second group of circuit elements;
- simulating operation of the second electronic circuit to determine second data representing values of signals in the second electronic circuit;
- determining a first signal corresponding to the first group of circuit elements;
- determining a first time period corresponding to a first value of the first signal;
- determining, using the circuit-element transformation technique, at least one second signal corresponding to the second group of circuit elements, wherein the second signal, at a second time period, corresponds to a representation of the first value;
- and
- determining using at least one value of the at least one second signal during the second time period and the circuit-element transformation technique, the first value,
- wherein the circuit-element transformation technique records a correspondence between the first group of circuit elements and the second group of circuit elements, the correspondence enabling a reverse transform to derive the first value from simulated values of signals of the second electronic circuit.
