A Symbolic Layout Generator for CMOS Standard Cells Using Artificial Intelligence Approach

인공지능 기법을 이용한 CMOS 표준셀의 심볼릭 레이아웃 발생기

SLAGEN, a system for symbolic cell layout based on artificial intelligence approach, takes as input a transistor connection description of CMOS standard cells and environment information, and outputs a symbolic layout description. SLAGEN performas transistor grouping by a heuristic search method, in order to minimize the number of separations, and then performs group reordering and transistor reordering with an eye toward minimizing routing. Next, SLAGEN creates a rough initial routing in order to guarantee functionality and correctness, and then improve the initial routing by a rule-based approach.
