Abstract

As data-path chips such as microprocessors and RISC chips become more complex, multiple stacks of data-path macros are required to implement the entire data-path. The physical decomposition of a chip into a single data-path stack, and control logic of random logic as in the past is not always feasible. This paper describes a special multi-stack structure, optimization techniques and algorithms to partition, place and wire the data-path macros in the form of the multi-stack structure, taking into account the connectivity of the entire chip logic (data-path, control logic, chip drivers, on-chip memory). The overall objective is: (1) to fit the circuits within the chip, (2) to ensure data-path wireability, including stack to random logic wireability, and (3) to minimize wire lengths for wireability and timing. A tool for automatic multi-stack optimization has been implemented and applied successfully to layout some high density data-path chips.

Partitioning and floor-planning for data-path chip (microprocessor) layout

Data-path chips are typically made up different types of objects such as data-path macros, control logic cells (e.g. standard-cell), memory arrays, and off-chip drivers. Each type of object is quite different than the other type in terms of size, shape, ...
