Title: Automatic general wiring method for integrated circuit
Inventor: HIRAGA TAKEFUMI
IPC: G06F17/50
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To perform arranging and wiring process in a short time by largely decreasing the probability of impossible wiring by detailed wiring process. SOLUTION: A chip is divided into lattices (S51), wiring capacity is computed (S52) and the number of usable grids is computed (S53). Then, one wiring congestion degree is computed (S54), the grid using rate is computed (S55) and the path where the cost is minimum is determined (S56). The above described steps S53-S56 are repeated until the net that is not wired disappears (S57). Then, whether the lattice boundary where the number of the passing wirings exceeds the wiring capacity is present or not is judged (S61). When the boundary is not present, whether the lattice, wherein the estimated grid using rate exceeds the number of the usable grids, is present or not is judged (S63). When the lattice is not present, the general wiring process is finished. when the lattice is present, the net is removed (S62 and S64), and the process is returned to the step S54.

The qualitative analysis is also possible from the patterns of the spectra obtd. by Fourier transform. The quantitative analysis is possible as well by making use of the fact that the intensity ratio of the basic wave component obtd. by the Fourier transform and the higher harmonic component has a specified relation with the concn. of the material to be inspected.

Title: Cyclic filter
Inventor: KONISHI KAZUO
IPC: H03H17/04
Filed: 1988-03-31
Abstract: PURPOSE:To reduce the scale of the hardware constitution of the title filter by adding temporal information to the amplitude information (bit number direction) of factor data so that a factor which is high in accuracy in a false state can be obtained. CONSTITUTION:Digital data inputted to the input section 11 of a cyclic filter section 17 are latched by a latch circuit 13 after cyclic data are added to the digital signals at an adder 12. The output data of the circuit 13 are led to an output section 14 as a filter output and, at the same time, supplied to a multiplier 16 where the data from the section 14 are multiplied by factor data from a selector 20. The multiplied results are supplied to an adder 12 as cyclic data. When the factor data supplied to the multiplier 16 are changed in a time division state in the course of the above-mentioned operations, factors of accuracy expressed by a number of bits larger than the actually utilized number of bits can be obtained in average. Therefore, the accuracy of the factors can be raised with a less number of bits and, as a result, it is not required to expand the scale of the hardware.
