摘要： A design support apparatus for semiconductor devices that is used to quickly arrange a non-logic cell for reducing electromagnetic radiation from a semiconductor device at the time of designing it. In this design support apparatus for semiconductor devices, a layout section does a layout for logic cells and wiring patterns to connect the logic cells. An arranged site detecting section detects an arranged site, being a site which contains neither the logic cells nor a prohibited area, after a layout is done by the layout section. A non-logic cell pattern store section stores non-logic cell patterns. A prohibited area containing site detecting section detects a prohibited area containing site, being a site which only contains a prohibited area. A non-logic cell arranging section arranges non-logic cells on the arranged site. Furthermore, the non-logic cell arranging section compares the arrangement of the prohibited area on the prohibited area containing site with a non-logic cell pattern and arranges non-logic cells only on a site where these do not conflict with each other.

摘要： A method for designing an integrated circuit such as a VLSI circuit, in particular optimizing delay of a signal transmitting through signal lines connecting a signal supplying source to each of elements, whereby skew can be decreased. The method can include determining whether the signal source satisfies a fan-out restriction if the signal source supplies a signal to all of the driven elements which are directly connected to the signal source, dividing the elements into groups so that the fan-out restriction is satisfied in each of the groups and each of the groups has the same or substantially same load capacity, when the signal source does not satisfy the fan-out restriction, and inserting into each group, a buffer having a size which makes the groups of elements satisfy the fan-out restriction. The dividing and the buffer inserting are repeated until a positive determination is delivered on the fan-out restriction.

摘要： There is provided a method utilized when designing an integrated circuit such as a VLSI or the like. The method is utilized for optimizing the delay of a signal transmitting through signal lines connecting a signal supplying source to each of elements, whereby skew can be positively decreased. The method includes a step (S511) of determining whether or not the signal supplying source satisfies a fan-out restriction if the signal supplying source supplies a signal to all of the driven elements which are directly connected to the signal supplying source, a step (S514) of dividing the plurality of elements into a plural number of groups so that the fan-out restriction is satisfied in each of the groups and that each of the groups has the same or substantially the same load capacity, when it is determined that the signal supplying source does not satisfy the fan-out restriction, and a step (S515) of inserting into each of the groups, a buffer element having a size which makes the groups of elements satisfy the fan-out restriction. The buffer element inserted at the buffer inserting step (S515) is regarded as a driven element and then it is again determined in the determining step (S511) whether or not the signal supplying source satisfies the fan-out restriction under the condition that the signal supplying source supplies a signal to all of the driven elements which are directly connected to the signal supplying source. The dividing step (S514) and the buffer inserting step (S515) are repeatedly carried out until positive determination is delivered on the fan-out restriction.
