Abstract

The invention provides a script generation method for a parameterization unit, which comprises the following steps of: 1) importing a layout design category which comprises a geometric figure category, an entity operation category and an attribute category; 2) defining parameter attributes and default values of the parameterization units; 3) designing parameterized unit contents by defining an evaluation function; 4, a global compilation function is called, and the layout name of the parameterization unit and the name of a layout library to which the parameterization unit belongs are definited.The script programming step of the parameterization unit is simplified, the script language can be flexibly selected under the same architecture, the design threshold of the parameterization unit can be lowered, and the parameterization unit script can be rapidly generated.

Description

technical field [0001] The invention relates to the technical field of semiconductor design and production, in particular to a script generation method for parameterized units. Background technique [0002] Whether it is a new process, or the special needs of customers on an existing process, semiconductor manufacturing companies need to quickly provide a process design kit (PDK) before mass production can be introduced. In fact, the content of the process design package is to provide the parameterized cell library required for the design as the main part. [0003] At present, the design method of the parameterized unit can be carried out in the way of script program programming, and the script is translated into the parameterized unit database through the compiler program. Parametric cell development is actually a kind of parametric layout design. Parametric cell designers need certain professional knowledge for the construction mode of hierarchical geometric figures, and ...
