The Pivotal Module Physical Design Of YHFT-DX

With the development of the IC design technology and manufacturing process, the problem of timing convergence is more and more difficult. Because the increasing of interconnection delay and chip integration produce capacitive and inductive coupling of interconnects, the load model turns to inaccurate in the design of deep submicron circuits, and it causes the problem of timing convergence and closure in physical design. The complex chip can be designed with the technology of module integration, And this technology is used in the YHFT-DX design. ASIC&full-custom design can improve the performance. And the development of manufacturing process needs more requirement in design reliability.The main results of this thesis can be expressed as follows.1. The technology of ASIC&full-custom design is used in module physical design.This paper presents the flow of ASIC&full-custom design, including the technological of reference library and Time module creation.2. This paper achieves the design of YHFT-DX address compute parts with ASIC&full-custom technology .The performance between ASIC&full-custom technology and ASIC technology is compared.3. The performance of register file is very important. The bypass module of register file can improve the performance. The bypss module is designed with full-culstom technology. This paper presents the mothodolory of circuit design with limited circuit technology. The layout design and the post-layout work is also presented.4. Cache module has many standed cells and macro cells. The timing problem and reliability of physical design is complicated. This paper makes detailed analysis of floorplan, placement, CTS, route. The reliability of physical design, for example power/ground network, Signal Integrity, Antenna effect is analysed and resolved.
