Title: Method of checking number of fan-out
Inventor: YAMADA SHUICHIRO
IPC: G06F17/50
Filed: 1985-11-18
Abstract: PURPOSE:To check efficiently number of fan-outs by providing the logical stage number provision step and the fan-out number check step. CONSTITUTION:The logical stage number provision step 101 provides the logical stage number representing the connection stage number from an output terminal of a logic circuit as to each circuit component on a connection path consecutive from the output terminal of the logic circuit. The fan-out number check step 102 checks the number of fan-outs as to each circuit component in the descending logical stage number at each connection path. Thus, since the output side subject already to the fan-out number check receives no effect even when the circuit is corrected due to exceeded fan-out number, only the fan-out number check is enough to one circuit component.

Filed: 1992-09-29
Abstract: PURPOSE:To improve the accuracy of plotting, and to shorten a plotting time by recognizing the assembly of pattern cells continuously arranged plural times and pattern blocks discretely disposed plural times and compressing pattern data. CONSTITUTION:Mats and cells arranged plural times are extracted from design pattern data 8, and graphic processing 10 is carried out. Consequently, processing 11, in which pattern data are prepared after compression, is executed to pattern data after obtained graphic processing. Compression means that the pattern data are divided into repetitive patterns and non-repetitive patterns and the repetitive patterns are partitioned into basic patterns and repetitive information thereof at that time. Accordingly, the repetitive patterns are displayed by the basic patterns and the repetitive information, thus reducing the quantity of lithography data.
