A system and method for integrated circuit design are disclosed to enhance manufacturability of circuit layouts through generation of hierarchical design rules which capture localized layout requirements. In contrast to conventional techniques which apply global design rules, the disclosed IC design system and method partition the original design layout into a desired level of granularity based on specified layout and integrated circuit properties. At that localized level, the design rules are adjusted appropriately to capture the critical aspects from a manufacturability standpoint. These adjusted design rules are then used to perform localized layout manipulation and mask data conversion.

An ultra wide bandwidth, high speed, spread spectrum communications system uses short wavelets of electromagnetic energy to transmit information through objects such as walls or earth. The communication system uses baseband codes formed from time shifted and inverted wavelets to encode data on a RF signal. Typical wavelet pulse durations are on the order of 100 to 1000 picoseconds with a bandwidth of approximately 8 GHz to 1 GHz, respectively. The combination of short duration wavelets and encoding techniques are used to spread the signal energy over an ultra wide frequency band such that the energy is not concentrated in any particular narrow band (e.g. VHF: 30-300 MHz or UHF: 300-1000 MHz) and is not detected by conventional narrow band receivers so it does not interfere with those communication systems. The use of pulse codes composed of time shifted and inverted wavelets gives the system according to the present invention has a spatial resolution on the order of 1 foot which is sufficient to minimize the negative effects of multipath interference and permit time domain rake processing.

In a DC-DC converter, the cooling of switching elements has been performed only by means of a cooling plate; therefore, there is a problem in that, to effectively radiate heats generated by power MOSFETs that have large heating values and that are arranged parallel, it becomes necessary to reduce thermal resistances and complicate the cooling route of a water-cooling device. Plural switching elements for controlling currents flowing through inductor elements, which are used for voltage conversion of a DC-DC converter, are fixed to a metal case via a heat conductive insulating material and via a metal radiator having a better heat conduction characteristic than the metal case. Because there occur no large mixing phenomena of heat currents among neighboring switching elements, and there are only little heat interferences between the neighboring switching elements, the thermal diffusion characteristic is improved, and the cooling efficiency for the switching elements can be increased.
