Standardized IP core evaluating method and system

Abstract

The invention discloses a standardized IP core evaluating method and a system, and the evaluating method comprises the following steps: S1, searching out relevant parameters of deliverable items between soft core and hard core of an IP core after standardization and firm core; S2, as for the soft core, hard core and firm core, on the basis of national IP core standard, utilizing scores to represent importance level of each quality measurement item of the deliverable items of the soft core, hard core and the firm core, and summating evaluating scores of all quality measurement items to obtain the quality total score of the deliverable items of the soft core, hard core and firm core; and as for an IP core source file, packing the file and inputting the packed file to an EDA automatic evaluating system for evaluation to obtain an evaluation result; and S3, comparing the quality total score of the deliverable items of the soft core, hard core and the firm core obtained in step S2 with theevaluation result of the EDA automatic evaluating system, if the two are inconsistent, determining the evaluation to fail, otherwise carrying out grade estimation on the IP core. The invention provides reliable quality evaluation basis for IP core business and ensures reliability and high reusability of the IP core.

Description

technical field [0001] The invention relates to the field of integrated circuit key technology services, in particular to a standardized IP core evaluation method and system. Background technique [0002] IP core refers to a hardware description language program with specific circuit functions. This program has nothing to do with the integrated circuit process and can be transplanted to different semiconductor processes to produce integrated circuit chips. The IP core delivery item refers to when the IP core is evaluated. The relevant data core files of the IP core design code, documents, scripts, etc. submitted by the IP developer to the IP core evaluation agency. With the rapid development of SoC (System on a Chip, system-on-a-chip), the effective multiplexing of IP cores has become the key to successful SoC design and shortening the design cycle. Along with the promotion and use of IP cores, a series of problems that need to be solved have also emerged: first, what kind ...

Problems solved by technology

Along with the promotion and use of IP cores, a series of problems that need to be solved have also emerged: first, what kind of documents should IP core suppliers provide to enable IP core users to select IP cores more conveniently and accurately; secondly, When the users of the IP core are not familiar with the structure of the IP core, how to quickly optimize it to meet the new design requirements; in addition, because the communication standards between SoC modules are often not uniform, resulting in IP core integration and effective difficulty of verification, etc.

At present, there is no unified standard in the world to clearly define IP core delivery items and evaluation reports
