From Time domain to Atm domain, the complete digital signal processing required by ADSL technology has been integrated onto a single device called SACHEM. High programmability along with flexible architecture enable the device to serve for both network and line termination. Mapping on a 0.35 /spl mu/m standard digital CMOS technology makes SACHEM a cost effective solution as well as a low power device, consuming only 800 mW at 3.3 V.

This paper covers the motivations for and the advantages of using an embedded DRAM compiler technology within a standard deep submicron logic process for System-on-a-Chip (SoC). We also discuss the bit cell design and the memory architecture, as well as the automation software and methodology used in the construction of the DRAM compiler. Silicon results from the test chips are favorable. This approach makes economical and time-to-market sense, therefore it can be a viable high-performance and area-efficient option in the embedded DRAM technology.

Optimum repeater insertion based on a CMOS delay model for on-chip RLC interconnect 基于CMOS延迟模型的片上RLC互连中继器最佳插入
Pub Date : 1998-09-13 DOI: 10.1109/ASIC.1998.723040

A closed form expression for the propagation delay of a CMOS gate driving a distributed RLC line is introduced that is within 7% of SPICE simulations for a wide range of RLC loads. This expression is based on the alpha power law for deep submicrometer technologies. It is shown that the error in the propagation delay if inductance is neglected and the interconnect is treated as a distributed RC line can be over 30% for present on-chip interconnect. It is also shown that the traditional quadratic dependence of the propagation delay on the length of the interconnect for RC lines approaches a linear dependence as inductance effects increase, which is expected to have a profound effect on traditional design methodologies. The closed form CMOS delay model is applied to the problem of repeater insertion in RLC interconnect. Closed form solutions are presented for inserting repeaters into RLC lines that are highly accurate with respect to numerical solutions. It is shown that large errors in the repeater design process are encountered if inductance is neglected. Errors up to 30% can occur if repeaters are inserted without considering the effects of inductance. The error between the RC and RLC models increases as the gate parasitic impedances decrease. Thus, the importance of inductance in high performance VLSI design methodologies will increase as technologies scale.
本文介绍了驱动分布式RLC线路的CMOS栅极传播延迟的封闭表达式,该表达式在大范围RLC负载下的SPICE模拟误差在7%以内。该表达式基于深亚微米技术的alpha幂律。研究结果表明,对于目前的片上互连,如果忽略电感,将互连作为分布式RC线处理,其传输延迟误差可达30%以上。研究还表明,随着电感效应的增加,RC线的传播延迟对互连长度的传统二次依赖关系接近线性依赖关系,这有望对传统的设计方法产生深远的影响。将封闭形式的CMOS延迟模型应用于RLC互连中中继器的插入问题。给出了将中继器插入RLC线路的封闭解,该解相对于数值解具有很高的精度。结果表明,如果忽略电感,在中继器设计过程中会遇到较大的误差。如果插入中继器而不考虑电感的影响,误差可达30%。RC和RLC模型之间的误差随着栅极寄生阻抗的减小而增大。因此,电感在高性能VLSI设计方法中的重要性将随着技术规模的扩大而增加。

The first two papers discuss novel buffer designs. One driver uses a capacitance feedback to control the output slew, reducing the power noise. The other buffer design utilizes a new CMOS logic circuit with a unique delay propagation characteristic that makes it much faster than conventional CMOS logic. There are two papers on SRAM circuit techniques. One paper presents a new approach based on current-mode to reduce energy and improve the speed of write and read access in multi-port SRAMS. The other SRAM paper presents a new currentmode sense amplifier design which can be used in the design of a low-voltage low power SRAM for ASIC applications.

Computer-aided design is central to ASIC design, supporting the design process from specification to implementation. The papers presented in this year’s CAD session reflect the broad importance of CAD in the ASIC design process, with papers addressing both the application of ASIC EDA tools, complete tool suites, and the algorithms they use. The session opens with a case study by Alcatel and Toshiba on CAD design methods for million gate systems. The session then addresses the application of CAD tools for the design of a Fast Discrete Cosine Transform and an embedded DRAM compiler for systems on a chip. Automatic layout synthesis and power estimation are covered in the next two papers. The first describes automatic layout of dynamic CMOS circuits and the second describes architectural estimation of power dissipation in processor control units. Finally the session closes with the presentation of papers on CAD algorithms, including a paper on incremental rerouting of mapped FPGA circuits and two papers on VLSI circuit partitioning. The first applies TABU intelligent problem solving to bipafl itioning, while the second reports on improved wirelengths by relaxing the traditional bisection constraint.

Relaxed partitioning balance constraints in top-down placement 在自上而下的布局中放松分区平衡约束
Pub Date : 1998-09-13 DOI: 10.1109/ASIC.1998.722911
A. Caldwell, A. Kahng, I. Markov
Recent work of Simon and Teng (1997) observes that the recursive bisection (i.e., bipartitioning with equal partition target areas, and minimum possible allowed deviation from targets) heuristic for k-way minimum-cut graph partitioning can have unbounded error, but that relaxing the balance constraints in each call to the bipartitioning engine can result in k-way net cuts within a small (O(logk)) factor of optimal. Motivated by this result, we experimentally determine whether relaxing the traditional exact bisection constraint in a top-down partitioning-based placement tool can improve the resulting cutsizes, and hence total wirelength, of the placement solution. We find that this simple change reduces total wirelength by up to several percent, with no change in placement uniformity and under 10% runtime penalty. Finally, we observe that the stability (predictability) of the placement process appears unimpaired by this modification: both wirelength stability, and stability of Rent parameter based wirelength and wireability estimates, appear to be preserved.
Simon和Teng(1997)最近的工作观察到,k-way最小分割图划分的递归二分法(即具有相等分割目标面积的双分割,并且允许与目标的最小偏差)启发式可能具有无界误差,但是放松每次调用双分割引擎的平衡约束可以导致k-way网络切割在一个小(O(logk))的最优因子内。受此结果的启发,我们通过实验确定了在自上而下的基于分割的放置工具中放松传统的精确平分约束是否可以改善所得到的切割尺寸,从而改善放置解决方案的总长度。我们发现,这种简单的改变将总长度减少了几个百分点,而布局均匀性没有变化,运行时间损失不到10%。最后,我们观察到放置过程的稳定性(可预测性)似乎没有受到这种修改的影响:无论是波长稳定性,还是基于Rent参数的波长和可达性估计的稳定性,似乎都得到了保留。

A new CMOS low-power mixed A/D ASIC for radiation detector readout front ends is presented. First, we recall the principle of radiation detection system before describing the whole architecture of the circuit. The discussion is then focused on the low-power issue. By means of an innovative 128:1 analog multiplexer, we show how we drastically reduced the mean power consumption without sacrificing constraining specifications such as the input range and the readout rate. Testing mixed A/D, but strongly analog IC is also a big issue which is addressed here. Specific built-in test analog sub-circuits have been implemented in the ASIC, along with a JTAG module used to choose the type of test to perform. This module is also used to control and tune the biasing currents of the circuit. Finally, test results are presented and show that all the specifications are satisfied.

First, we recall the principle of radiation detection system before describing the whole architecture of the circuit. The discussion is then focused on the low-power issue. By means of an innovative 128:1 analog multiplexer, we show how we drastically reduced the mean power consumption without sacrificing constraining specifications such as the input range and the readout rate. Testing mixed A/D, but strongly analog IC is also a big issue which is addressed here. Specific built-in test analog sub-circuits have been implemented in the ASIC, along with a JTAG module used to choose the type of test to perform. This module is also used to control and tune the biasing currents of the circuit. Finally, test results are presented and show that all the specifications are satisfied.","PeriodicalId":104431,"journal":{"name":"Proceedings Eleventh Annual IEEE International ASIC Conference (Cat.
