Prof. Ricardo Reis ministra tutorial no IEEE NEWCAS 2025

O professor Ricardo Reis, do Instituto de Informática da UFRGS, participa do IEEE NEWCAS 2025, realizado de 22 a 25 de junho em Paris, França, ministrando o tutorial:

“Physical Design Automation: Learning from the Past and Challenges”

Abstract:
By the end of years 70s, microprocessors were designed by hand showing excellent layout compaction. It will be shown some highlights of the reverse engineering of the Z8000, which control part was designed by hand, showing several layout optimization strategies. The observation of the Z8000 layout inspired the research of methods to do the automatic generation of the layout of any transistor network, allowing to reduce the number of transistors to implement a circuit, and by consequence, the leakage power. Some of the layout automation tools developed by our group are briefly presented. A way to reduce power consumption is to reduce the number of transistors used to implement a circuit, as leakage power is proportional to the number of transistors. It is shown a physical design approach to reduce the number of transistors needed to perform a task. It is proposed an EDA tool set to automatically generate the physical design of any transistor network. It shows an important reduction on power, improving also reliability. A standard cell library has a limited number of logical functions, and a limited number of sizings. The talk is target in optimization methods to reduce the number of transistors of a circuit. The methods allow the realization of any possible logical function or transistor network. It is included comparisons with solutions using the traditional standard cell methodology.

Além do tutorial, o professor Reis também apresentará o artigo:
