Technical Field
The invention belongs to the technical field of EDA modeling, and particularly relates to a correlation updating method, a correlation updating system and a correlation updating medium for EDA modeling.
Background
The associated update in EDA model modeling is an important technology, and plays a key role in realizing the consistency of the model and the data update. The association update ensures that the data in the model always keeps synchronous and accurate by processing related events and association relations. While there are many advantages to association updating, there are some potential problems and challenges with existing association updating methods, which face performance and efficiency challenges for handling complex models with a large number of associations and data interactions. When the association relationship is large and the data amount is huge, the update process becomes time-consuming. The complexity of locating and updating the relevant data may lead to performance degradation. Performance optimization and reasonable data structure design are needed to improve the efficiency of association update. The association in the model may sometimes form a loop dependency, where an update of one entity may trigger an update of another entity, which may trace back to the first entity, thus forming an infinite loop. Circular dependencies may cause the system to enter a deadlock state or fail to operate properly. A design mechanism is needed to handle the loop dependencies and ensure the stability of the system.
For example, chinese patent application number CN201810759464.9, publication date is 2019, month 2, and day 19, discloses a system and method for controlling a guiding and controlling system based on dynamic modeling, wherein the system includes: the guide and adjustment module is used for generating a model creation command and transmitting the model creation command to the simulation engine; the model creation command carries a model mark and model parameters; the simulation engine is used for: receiving a model creation command transmitted by the pilot module, and creating a target model instance according to a model identifier and model parameters carried in the model creation command; and based on the model identification, acquiring an associated model identification parameter relation corresponding to the model identification, generating a running model parameter list of an associated model corresponding to the associated model identification according to the associated model identification parameter relation, updating parameters of the associated model by using the model parameter list, and simultaneously putting a target model instance into operation. The disadvantage of this patent is that: although the model can be dynamically created, the accuracy and stability are still to be considered.

Detailed Description
The invention is further described below in connection with specific embodiments and the accompanying drawings.
Example 1
Referring to fig. 1 and 2, fig. 1 is a schematic flow chart of the present application; FIG. 2 is a diagram of a data structure and associated data mapping representation of the present application.
As shown in fig. 1 and 2, in this embodiment, an association updating method for EDA model modeling includes the following steps:
s1: creating a model (shape) and a modeling command (cmd) respectively: wherein each model has a unique ID and a body ID; each modeling command has a unique ID and tagID;
it is described that each model has a unique ID, and the ID is used for identifying each model; the body ID is the main body ID and is mainly used for indexing geometric data, so that quick association is facilitated, and the efficiency is improved; the ID of the modeling command is also the identification of each modeling command, and tagID is the index identification information, which is used to represent the state of the modeling command. For tagID, the tagID of each modeling command (cmd) is related to a global self-increasing static variable, for example, when no modeling command is performed on a model, the initial value of the static variable is 0, when a modeling command operation is performed on a certain model, a modeling command (cmd) is created, the tagID of the modeling command (cmd) is assigned to the static variable, that is, the tagID value is 0, then the static variable is self-increased by one, the value of the static variable itself becomes 1, and when a modeling command is performed on a subsequent model, the tagID of the newly created modeling command (cmd) is assigned to the value of the current static variable, that is, the tagID value of 1, and so on, the time sequence of the modeling operation can be represented by the size relationship of the tagID of each modeling command (cmd).
S2: classifying modeling commands; the modeling command comprises an ontology command only changing the model itself; and the model itself generates associated commands associated with other models;
specifically, the associated command comprises a copy type command and a Boolean type command; boolean commands, such as sub/unite/split, etc.; copy commands, such as move+/rotate+/mirror+ and the like, which generate new shapes and influence the new shapes after the geometric changes of the shapes bound with the commands;
the body commands comprise a creation type command, a matrix type command and a Surface type command; a create command such as a creation command of a line facet; matrix commands, such as move/mirror/rotate/scale, update of shape geometry data only needs to perform matrix conversion and does not interact with other shapes; surface type commands, commands that rely on the geometry data of the shape themselves, operate to cause changes in the shape's geometry data itself, such as moveFaces, sweepFace commands, and the like.
S3: creating a mapping relation table between the model and the modeling command;
each model has a one-to-many mapping relation with modeling commands, the mapping relation is stored in the map, and each modeling command stores relevant parameters during operation, so that follow-up tracking is facilitated;
s4: creating a model mapping relation table of the association command;
specifically, creating the model mapping relation table of the association command includes creating a model mapping table of the copy association: in the modeling process, one shape is possibly created by carrying out translation copy, mirror image copy, rotary copy or scaling copy on another shape, and the clone of the copied shape is updated along with the update of the geometric data of the copied shape, so that the clone can be quickly indexed by establishing a shape mapping relation of copy association, and the effect of quick update is achieved;
and creating a model mapping table in which boolean associations exist: in the modeling process, one shape (blank shape) may be obtained by performing boolean operations with other shape (tool shapes), such as sub, unite, split or imprint, and the geometric data of tool shapes are updated so that the blank shape is updated accordingly, so that the blank shape and the tool shape can be quickly indexed by establishing a shape mapping relation of boolean association, thereby achieving the effect of quick updating.
S5: when a modeling command is created, updating geometric data of a model;
specifically, the specific operation of updating the model geometry data is as follows: constructing a 4*4 matrix when carrying out translation, rotation, mirroring and scaling operations on the model, and updating geometric data of the model; when the operation parameters are updated, geometrical state backtracking is carried out by utilizing the rectangle, and then the matrix is reconstructed to update the model geometrical data;
s6: and carrying out association update on the model: starting from the initial model, acquiring all associated models according to a model mapping relation table of the associated commands; obtaining mapping relation tables between all the association models and modeling commands according to the mapping relation tables between the models and the modeling commands; and then updating all the association models until all the association models are updated.
Specifically, in the step, a mode of breadth first search based on a directed graph is adopted to update the model in an associated mode, and all associated models are obtained from a starting model according to a model mapping relation table of an associated command, namely a copy associated model mapping table and a Boolean associated model mapping table; obtaining a relation mapping table between all the associated models and modeling commands according to the relation mapping table of the models and the modeling commands;
sequencing according to tagID of the last modeling command associated with the model, sequentially updating all acquired associated models through a mapping relation table between the associated models and the modeling command; it is illustrated here that because the association update of a model involves updating a number of associated models, i.e. associated models; when the associated models are updated, the updating sequence is consistent with the creation sequence of the models, the tagIDs of all modeling commands have a size relationship, the descending-to-ascending ordering sequence of the tagIDs represents the creation sequence of the modeling commands, and therefore, the tagID size relationship of the last modeling command of all the associated models represents the creation sequence of the models; so in order to ensure the sequency of the model association update, the tagID of the last modeling command of the model is utilized for sorting, so that the model is updated, and the purposes of good model updating effect and order assurance are achieved; and marking the updated model as accessed and adding it to the queue for the next access; repeating the steps until all the association models are updated.
According to the method, modeling commands are classified, mapping relations of different types of modeling commands are constructed, and the searching efficiency of the association model is improved; meanwhile, a tagID is set for modeling commands to define the time sequence of modeling operation, so that the situation that a ring structure appears in breadth-first searching, and the system possibly enters a deadlock state or cannot normally run due to dead circulation is avoided; the whole method can quickly update the geometric data of the complex model with a large number of association relations and data interaction, and improves the user operation experience, so that the efficiency and the performance of association update are both considered.
