Method for technology transplant of analog circuit

Abstract

The present invention discloses a method for the technology transplant of an analog circuit, wherein the method comprises: receiving the data assigned by a user in the form of graphical interface or command line; analyzing and dividing the data based on the circuit functions of analog circuit function structure characteristic database to generate a new hierarchical design based on functions; generating constraint conditions based on the function structure characteristics; generating a test circuit based on the test circuit template database of the analog circuit function performance indexes; generating measure instructions based on the measure instruction template database of analog circuit function performance indexes; calculating the performance index values by using the performance index value test circuit and the measure instructions; mapping the original technology to the object technology by using the hierarchical design based on functions; performing the parallel optimization of the object circuit from bottom to top by using the independence between the hierarchical design units based on functions; and outputting the optimized hierarchical circuit design netlist based on functions under the object technology. An analog circuit having been designed under a technology is automatically optimized to an analog circuit in which the circuit performance index values accord withthe requirement under another technology by utilizing the invention.

Description

technical field [0001] The invention generally relates to the technical field of electronic design automation (EDA) software, in particular to a method for transplanting an analog integrated circuit design under an integrated circuit technology (original technology) to another integrated circuit technology (target technology). Background technique [0002] The process of optimizing an integrated circuit under the original process into an integrated circuit under the target process through a series of treatments is referred to as process transplantation. Fortunately, process migration has been used in digital circuit design for many years. While process migration is particularly mature in digital circuit design, process migration automation is still in its infancy for analog circuit design. In the prior art, the migration of analog circuit technology is mainly completed by circuit designers with the help of SPICE (Integrated Circuit Simulation Program). As a preliminary stu...
