Abstract(in English) | As the feature size of VLSI becomes smaller, delay variations become a serious problem in VLSI design. The "setup" timing constraint can be fulfilled by choosing a clock period appropriately, while the "hold" timing constraint can not, and in many cases, the hold constraint becomes critical for a correct latch of a signal under delay variations. An approach to ensure the hold constraint under delay variations is to enlarge the minimum path delay between registers. It can be done by inserting delay elements on non-critical paths mainly in a functional unit. We call it "minimum path delay compensation" in this paper. This paper discusses the RT-level optimization problem to minimize the number of functional units which require minimum path delay compensation in datapath synthesis, and computational complexities and computation algorithms for this problem are revealed and proposed. |
