Description

The electronic circuit module management method of RF IC

Technical field

The present invention relates to a kind of electronic circuit module management method of RF IC, particularly the electronic circuit module management method of the RF IC in the design of using 3 D electromagnetic field simulation analysis.

Background technology

RF IC is meant the radio circuit that uses the semiconductor integrated circuit technique fabrication techniques, and it is little, low in energy consumption to have a volume, characteristics such as reliability height.Common radio circuit has: low noise amplifier, power amplifier, oscillator; Frequency mixer etc.; Frequency of operation from hundreds of MHz to several GHz, tens GHz do not wait, and are the very important signal processing modules of Wireless Telecom Equipment, its performance quality directly influences product quality.

In recent years, the wireless communication technology development is rapid, and wireless product is widely used in the various aspects of people's life, and RF IC is also had higher requirement, and requires to have more excellent signal handling capacity and shorter product development cycle.

RF IC mainly is made up of passive devices such as transistor active device and inductance capacitances, and according to traditional design method, the deviser at first formulates the performance parameter of RF IC according to system requirements; Confirm circuit structure picture schematic diagram, confirm that with circuit simulation the parameter designing of schematic diagram is correct, again according to circuit theory picture domain; Accomplish the contrast checking that domain need carry out domain and schematic diagram afterwards; To confirm the correctness of domain, then extract the parasitic parameter of domain and do post-simulation, if the result of post-simulation is undesirable; Then return the schematic diagram optimal design parameter; Revise corresponding domain simultaneously, continue then to extract the parasitic parameter of domain and do post-simulation, just send foundries to make chip if the result of post-simulation reaches the Expected Results of design.

Yet; Traditional design method is subject to its variation that can't consider the 3 D electromagnetic field; So in the high frequency field, be difficult to provide accurate simulation result, so; A lot of devisers improve the design that adopts IC design to combine with 3 D electromagnetic field simulation analysis on the method for traditional RF IC design.

This method for designing can obtain the emulation degree of accuracy higher than traditional design method, but in order to obtain higher simulation analysis efficient, carries out the emulation of 3 D electromagnetic field again after need a few sub-circuit modules being cut apart in a complete design usually.Therefore, how appropriately effectively way circuit to be cut apart, and the electronic circuit module after cutting apart is managed, become very important function in the RF IC design item.

Summary of the invention

Technical matters to be solved by this invention provides a kind of electronic circuit module management method of RF IC, and this method can be created a plurality of electronic circuit modules in original circuit model, and gets up the electronic circuit module management of creating.
