Step S20, storing the estimated design experience and the newly added risk rules in a background knowledge base, and judging the validity by detecting the reference number of the design rules.
Specifically, since the newly added risk rule is stored in the background knowledge base, all designers of the enterprise can query and quote in the design process, and the validity of the risk rule is judged through the quotation number of the designers (the rule is considered valid after the quotation value reaches a threshold value, and the rule is more valid when the quotation is more), namely a voting mechanism is adopted to reversely push the rule to upgrade so as to realize knowledge learning.

In the system, because reference document association is carried out on each design rule in advance, each risk identified by design evaluation can be related through a right key to check the reference information of the rule based on the risk, for example, the rule is refined based on what standard or failure case, a document list in the right key related check is ranked through the reference number of votes, and the higher the number of votes is, the higher the degree of association with the rule is; the system realizes the accurate matching inquiry of the reference document through a rule reference document seminal emission algorithm.
Referring to fig. 4, a flowchart of step S30 in the design rule processing method provided by the present invention is shown.
As shown in fig. 4, the step S30 includes:
s31, after detecting that a designer imports a design schematic diagram or a board layout diagram through design information, obtaining rule items expressed by a logic expression one by one in a background knowledge base;

(1) The specific implementation method of the rule reference document seminal emission algorithm is described as follows:
firstly, adopting a knowledge base form, splitting limit description of enterprises about schematic diagram or layout diagram design in a circuit board design specification into a plurality of quantitative clauses or carrying out statistical arrangement or qualitative description on quantitative data obtained through experimental test and failure analysis, then carrying out logical expression on the clauses to form a mathematical expression, storing design knowledge documents (including design specifications, experimental test documents, failure analysis documents and the like) forming the rule expression in a file system in a document library form, and simultaneously adopting two modes for associated storage, wherein one mode adopts an index mode to store index information of the documents to form a full-text index table SI, and the other mode adopts an associated table mode to store an implicit associated table RI of the rule table and a reference information document.
Firstly, inquiring from an association table RI through relation searching, if no corresponding item exists in the association table RI, indicating that an accurate association relation is not established, acquiring a similar reference document from an index table SI through full text fuzzy searching by a program, presenting the similar reference document to a user, selecting (voting) the searched reference document by the user, and carrying out accumulation sorting by the program according to identification bits by the confirmation, and simultaneously automatically adding an association record of the rule and the reference document in the association table; and performing a new round of sequencing by iterative accumulation voting, thereby gradually realizing reference accuracy.
(2) Rule generation and exit algorithm: the automatic maintenance and updating of rules in a Checklist library are realized by adopting a voting feedback mechanism in a program; the specific implementation method is described as follows:
the program generates a potential risk table after matching and screening the rule constraint conditions and the current design information, performs identification voting on each potential risk item R1 screened by the program, judges whether the rule S1 is smaller than 0 according to a voting real-time statistical formula, if so, indicates that the rule needs to be submitted for review and exit (if the review does not exit, preset statistical values are reset), and the statistical formula is as follows:
wherein: s1 is a calculated reference value of whether a design rule exits;
v0 is the preset ticket number of the preset rule;
v is a vote for approval (the item is selected as risk in the assessment);
a1 is an influence factor for approving the ticket;
e1 is the validity period of a preset rule;
ti is the current date of each vote;
t1 is the design rule effective date;
n is an objection ticket (the item is not selected as a risk in the assessment);
b1 is an impact factor against the ticket.
In addition, for a new rule NR, a certain client initiates input, the input information is stored in a background Checklist library (namely a background knowledge base), because the new rule NR is not strictly audited and can not be used as a formal rule, a user can enter a temporary rule library after manually inputting the new rule NR, the reference is distributed by adopting a weight factor (note: the weight factor is a proportional value reflecting the relative importance degree of a certain index in the overall evaluation) through a selection mode, if the weight factor referenced in the risk assessment stage is A, the reference weight factor continuously referenced in the risk measure processing stage is B, the reference weight factor continuously referenced in the risk confirmation stage is C, and finally the reference number S2 of the new rule NR is:
wherein: v0 is the preset ticket number of the preset rule;
v1 is the number of votes in the risk assessment stage;
v2 is the number of votes in the risk measure treatment stage;
v3 is the number of votes in the risk confirmation stage;
a2 is a risk assessment stage weight factor;
b2 is a risk measure processing stage weight factor;
c is a risk confirmation stage weight factor;
e2 is the validity period of a preset temporary rule (validity period of a normal rule);
ti is the current date of each vote;
t2 is the temporary rule effective date;
when the reference number S2 counted in real time is greater than a threshold value L (L is set to 1.5 times the number of electronic engineers (designers) in the enterprise, if the number of electronic engineers is less than 5, 8) then the rule is automatically transferred to the formal rule base, and when S2< = 0, the temporary rule is automatically cleared from the temporary rule base.
In the invention, a mode of rule reference documents adopts a dual search mode of full text search mode aiming at natural language description and accurate association based on a voting mechanism, a program automatically switches search orders according to weight factors, search precision is continuously improved according to a voting feedback mechanism, and the knowledge acquisition problem is solved; the voting mechanism based on the weight factors and the time axis is adopted to dynamically maintain the generation mechanism of the rule, so that the automatic iterative maintenance of the rule is realized, and the value of the rule is determined by the evaluation flow reference quantity; when the reference quantity reaches a certain value, prompting to turn positive, and solving the problem of knowledge sharing; the knowledge management and the design evaluation flow are seamlessly connected by the two methods, so that the value of knowledge management is directly reflected.
