Abstract
Parameter population of cells for a hierarchical semiconductor structure via file relation is disclosed. One aspect of the invention is a computerized system that includes a global file of global variables, a plurality of local files, and a plurality of cells. Each local file relates a plurality of local variables to the global variables. Each cell corresponds to a local file and has a set of parameters corresponding to the local variables of the local file.
Claims25
A computerized system comprising:
- a global file of global variables;
- a plurality of local files, each local file relating a plurality of local variables to the global variables;
- and,
- a plurality of cells, each cell corresponding to a local file and having a set of parameters corresponding to the local variables of the local file.
A computer-readable medium having a computer program stored thereon to cause a suitably equipped computer to update a set of parameters of a cell by relating local variables of a local file for the cell to global variables of a global file.
A computer comprising:
- a processor;
- a computer-readable medium;
- a global file of global variables stored on the medium;
- a plurality of local files stored on the medium, each local file relating a plurality of local variables to the global variables;
- and,
- a computer program executed by the processor from the medium to update a set of parameters for each of a plurality of cells having a corresponding local file by reading values for the global variables to which the local variables of the local file correspond.
A computerized method comprising:
- changing at least one of a plurality of design rules within a cleansheet file;
- updating values for a plurality of global variables of a global file based on the design rules of the cleansheet file;
- and,
- updating a set of parameters of a cell by relating corresponding local variables of a local file for the cell to corresponding global variables of the global file.
