Abstract

The invention discloses a method of reducing calculation complexity of equations in integrated-circuit design. The method is characterized by including the following steps: 1) determining tolerance ofcapacitance optimization; 2) traversing all capacitance devices; and 3) carrying our disconnection or a split on each traversed capacitance device according to the tolerance of capacitance optimization. According to the method of reducing the calculation complexity of the equations in integrated-circuit design of the invention, dimensionality of the equations can be reduced, the number of non-zero elements in a sparse matrix can also be decreased, coupling among rows in the equations can be reduced at the same time, thus the calculation complexity of the equations is reduced, and an overall design cycle of an electronic circuit is improved.

Description

technical field [0001] The invention relates to the field of integrated circuit automation product design, in particular to a method for reducing the computational complexity of equations in integrated circuit design. The invention is a method for optimizing the equation group in integrated circuit automation products, especially for the optimization of post-simulation circuits. Background technique [0002] The scale of equations in electronic circuits is an important factor restricting the performance of integrated circuit automation products. How to optimize the equations and how to reduce the computational complexity of the equations is a hot topic in current electronic circuit design. As the process continues to progress toward the nanoscale, the scale of the circuit is also expanding rapidly, and the scale of the corresponding equations is also increasing rapidly. If no optimization is carried out, the time and space consumption of the entire simulation will be great...
