Title: Layout design method
Inventor: ISHIOKA TAKASHI
IPC: H01L21/82
Filed: 1993-04-22
Abstract: PURPOSE:To change a circuit so as to reduce the fanout of a critical path, by performing delayed analysis after layout and extracting a critical path not satisfying specifications, performing fanout decomposition, adding group restrictions automatically, and changing the drive force of cells and excuting layout again. CONSTITUTION:A critical path is extracted by delayed analysis (11, 12), and fanouts of a specified or larger value out of nets of the critical path are chosen (14). Cells on the drive side are copied (16), and a circuit is changed so as to drive pairs of pins belonging to the critical path, and fanout decomposition is performed so as to decrease delay wiring capacities and the input capacities of cells. Besides, concerning the cells near to each other and those of the same output, the cells closely related to each other in respect of arranged positions or logical connection are collected into groups. Group restrictions are added on to the cells connected to the pairs of pins to suppress the extention of arranged positions (18). And layout is reexcuted on the basis of changed logic connection informations and restriction informations.

Filed: 1982-06-07
Abstract: PURPOSE:To improve a margin for noise, by detecting and decoding thresholds in N values only from information included in a receiving signal in respect of the N value signal including all the N values out of signals inputted to the titled device by dividing the N value signal as time sharing. CONSTITUTION:One sample in each bit is taken out from a storage device 3 storing only n-bits of an output from an A/D converter at m intervals and inputted to a difference detecting part 4 to detect the maximum difference value among the sample values. In case of the N value signal, (N-1) thresholds are found. The output of the difference detecting part 4 becomes (N-1) difference values. A detection part 5 detects the threshold values from the difference values and a discrimination part 6 discriminates the level of the detected threshold value in each bit on the basis of the sample values from the storage device 3. Said operation is repeated by m times. Since m-pairs of difference values and level-discriminated signal systems are sent to a data holding part 7, the difference between difference values is checked, and when a larger difference value is sent, all the data are exchanged to obtain the most precise discrimination result.
