Above description is made for the second connector, and however it is quite same for the first connector.
To prevent such shifts, a device is indicated in Japanese Patent A62-198,064. In the patent, a plurality of protuberances are arranged on a block which has chambers and is disposed in a housing, while a seal in which holes are formed is provided with a plurality of depressions. The depressions are engaged by the protuberances to prevent shifts of the holes of the seal from the chambers when wiring harnesses are inserted through the holes to the chambers.
Notwithstanding the disposition of the device, however, some holes of the seal shift due to shearing force induced by insertion of wiring harnesses.
As mentioned above, in the conventional connectors, it is difficult or impossible to get the wiring harnesses 17 through the holes 19, or good waterproofness can not be obtained. The present invention relates to the field of electronic design automation for integrated circuits, and in particular, to simultaneous place and route for analog design.
Integrated circuits are important building blocks of the information age and are critical to the information age, affecting every industry including financial, banking, legal, military, high technology, transportation, telephony, oil, medical, drug, food, agriculture, education, and many others. Integrated circuits such as DSPs, amplifiers, voltage converters, DRAMs, SRAMs, EPROMs, EEPROMs, Flash memories, microprocessors, ASICs, and programmable logic are used in many applications such as computers, networking, telecommunications, and consumer electronics.
Consumers continue to demand greater performance in their electronic products. For example, higher speed computers will provide higher speed graphics for multimedia applications or development. Higher speed internet web servers will lead to greater on-line commerce including on-line stock trading, book sales, auctions, and grocery shopping, just to name a few examples. Higher performance integrated circuits will improve the performance of the products in which they are incorporated.
Large modern day integrated circuits have millions of devices including gates and transistors and are very complex. As process technology improves, more and more devices may be fabricated on a single integrated circuit, so integrated circuits will continue to become even more complex with time. To meet the challenges of building more complex and higher performance integrated circuits,
