Abstract
The invention discloses a method for converting standard technical drawing into system modules in microcomputer systems. The invention first reads standard drawing documents from the standard technical drawing document, and then judges and reconstructs the structural information in the read component record information to identify various components, reads their connection relationship, calculates the screen coordinate of system components, and eventually generates the system document. In the process of judging and reconstructing structural information from the read component record information, the invention differentiates and handles the overlapping part of components, so as to convert actual rather than ideal technical drawing documents into system module documents, thus realizing the automatic transmission of data from technique to system.
Description
Technical field
The present invention relates to that the standard technology domain belongs to the MEMS (micro electro mechanical system) design field to the conversion method of system-level model in the MEMS (micro electro mechanical system).
Background technology
At present, be at first to draw the domain of device from the process level domain to system-level method of emulation in the MEMS (micro electro mechanical system), carry out after the corresponding DRC, manually build corresponding model and carry out performance simulation according to the domain that designs system-level.And a kind of more satisfactory method for designing is according to the direct automatic creation system level of standard edition map file model, can realize the conversion from the standard technology domain to system-level model automatically like this.
At document An Extraction-Based Verification Methodology for MEMS (JOURNAL OFMICROELECTROMECHANICAL SYSTEMS, VOL.11, NO.1, FEBRUARY 2002) in, people such as the Bikram Baidya of CarnegieMellon university have researched and proposed the direct abstracting method of a kind of domain, the information extraction from domain of this method, identification domain assembly, corresponding to the component library in system-level, thus set up system-level model.But its method does not provide the solution when between each assembly of technology domain lap being arranged.And in the actual design domain, overlapping situation often appears between the assembly, therefore, this method still can not be desirable finishes automatic conversion from the standard technology domain to system-level model.
Summary of the invention
In order to overcome the deficiency that prior art can not solve lap problem between each assembly of technology domain automatically, the present invention proposes the conversion method of a kind of standard technology domain to system-level model, come recognizer component by component parts in the analytical standard technology domain, the determination component type, the lap of resolution and processing components, the process level layout file is converted into the system-level model file, thus realize data from process level to system-level fast automatic transmission.Standard technology layout file of the present invention is the CIF form.
The technical solution adopted for the present invention to solve the technical problems of the present invention comprises following concrete steps:
Step 1: read the standard edition map file, comprise that component record information is two dimensional surface information and topology information, wherein two dimensional surface information comprises geological information such as length, width and position parameter data such as the center point coordinate of component parts; Topology information comprises structural sheet, anchor point layer and electrode layer information, and wherein the component distribution of broach capacitor assembly and anchor point assembly is at structural sheet and anchor point layer, and the plate condenser assembly is at electrode layer, and other assemblies are all at structural sheet.The fileinfo that reads simultaneously also comprises file header information and document end message, and file header information comprises macroparameter information and annotation information such as long measure, proportionate relationship; Document end message is an end mark.Macroparameter information in memory module recorded information and the file header information, file specifications such as place to go annotation information.
Step 2: with the component record information that reads in the step 1 is that structural sheet information in two dimensional surface information and the topology information is differentiated and reconstruct.Because when reality is drawn domain, in order to prevent that the disconnection meeting from lap occurring in the junction of interconnective component parts, but the geometric parameter of the component parts that provides when carrying out emulation is that part of length except that overlapping, wide, center point coordinate, so need be reconstructed to structural sheet information, its process is as follows: at first, calculate the length of the difference of center point coordinate of two parts and two parts or half of wide difference, the two is compared, if the former greater than the latter then two parts be not annexation, if the former equal the latter then two parts are annexations but do not have lap, if the former less than the latter then two parts are annexations and lap arranged; Then, the length and width that calculate the little rectangle of lap according to the center point coordinate and the length and width of two parts; At last, recomputate and store length and width and the center point coordinate of removing the component parts behind the lap.
Step 3: the various component parts of identification in the component record information of handling from step 2, promptly according to the component parts of every layer of topological structure identification, identify various component parts in the structural sheet according to the range scale of length breadth ratio and length and width.Because the broach capacitor is made up of a lot of broach in the structural sheet, identify each the broach parts that belongs to the broach capacitor assembly so need be the rule of equidistant distribution, and these broach parts are sorted according to position parameter data according to each broach parts of broach capacitor assembly.
Step 4: the annexation that reads the information after step 3 is handled, soon the identical parts of center point coordinate are mapped by mark in the different layers, to there be the parts of annexation to be mapped in the structural sheet simultaneously, and the various component parts that step 3 identifies are passed through the assembly name corresponding to the respective element in the system-level component library by mark.
Step 5: the position parameter data according to component parts in the layout file travels through each layer, the screen coordinate of computing system level element in system-level model.
Step 6: generation system level file.
At first, the macroparameter that system-level file is set comprises font, color etc.; Then, travel through every layer, export in the step 4 corresponding to the respective element in the system-level component library; The border of system-level model then, is set; At last, according to the screen coordinate that calculates each element in the step 5, and in the step 4 corresponding to the respective element in the system-level component library, the element in the output system level model.
The invention has the beneficial effects as follows: the present invention is by component parts recognizer component in the analytical standard technology domain, the determination component type, and the lap of assembly is differentiated and handled, thereby can be with actual conditions but not process level layout file ideally is converted into the system-level model file, overcome prior art and can not handle the deficiency of setting up lap, realized data from process level to system-level automatic transmission.
The present invention is further described below in conjunction with drawings and Examples.
