Abstract

대규모집적회로의 설계 방법에 관한 것으로써, 커스텀 LSI회로의 모듈간배선의 설계시간을 대폭으로 경감하기 위해, 라이브러리로써 등록된 모듈간을 LSI의 소정의 기능을 실현하도록 전부 접속한 결선완료회로데이타를 미리 설계해서 준비해둠과 동시에 각 모듈이 그 LSI칩상에 존재하지 않는 경우에 그 모듈로의 접속배선 종단을 어떠한 상태로 해둘지를 지정하는 미접속종단데이타도 작성해두고 신규 LSI의 개발시에 사용하는 회로모듈이 선택되었으면 결선완료회로데이타에서 사용하지 않는 모듈의 데이타를 삭제하고, 그 대신에 미접속종단데이타를 대입하도록 하였다.A design method for designing a large-scale integrated circuit. In order to significantly reduce the design time of inter-module wiring of a custom LSI circuit, the wiring completed circuit data in which all the modules registered as libraries are connected to realize a predetermined function of the LSI. Design and prepare the circuits beforehand, and create unconnected termination data specifying the state of termination of the connection wiring to the module when each module does not exist on the LSI chip, and use the circuit for the development of a new LSI. If a module is selected, the data of the unused module is deleted from the wiring completion circuit data, and the unconnected termination data is substituted instead.

이러한 방법을 이용하는 것에 의해, 미리 라이브러리로써 준비된 것 중에서 임의의 모듈을 선택해도 새로 그들을 접속하는 결선데이타를 설계할 필요가 없으므로 LSI의 개발기간이 단축됨과 동시에 배선미스가 없어져 TAT도 단축된다.By using such a method, even if an arbitrary module is selected from among those prepared as a library, it is not necessary to design the wiring data for connecting them newly, so that the development period of the LSI is shortened, the wiring miss is eliminated, and the TAT is also shortened.
