Description
This book was motivated by the problems being faced with shrinking IC process feature sizes.
It is well known that as process feature sizes shrink, a host of electrical problems like cross-talk, electromigration, self-heat, etc. are becoming important. Cross-talk is one of the major problems since it results in unpredictable design behavior.
In particular, it can result in significant delay variation or signal integrity problems in a wire, depending on the state of its neighboring wires.
Typical approaches to tackle the cross-talk problem attempt to fix the problem once it is created.
In our approach, we ensure that cross-talk is eliminated by design.
The work described in this book attempts to take an "outside-the-box" view and propose a radically different design style.
This design style first imposes a fixed layout pattern (or fabric) on the integrated circuit, and then embeds the circuit being implemented into this fabric.
The fabric is chosen carefully in order to eliminate the cross-talk problem being faced in modem IC processes.
With our choice of fabric, cross-talk between adjacent wires on an IC is reduced by between one and two orders of magnitude.
In this way, the fabric concept eliminates cross-talk up-front, and by design.
We propose two separate design flows, each of which uses the fabric concept to implement logic.
The first flow uses fabric-compliant standard cells as an im- plementation vehicle.
We call these cells fabric cells, and they have the same logic functionality as existing standard cells with which they are compared.
