DigiSeal - um estudo de caso para modelagem de transações temporais assíncronas na metodologia VeriSC.

Abstract

The necessity for more complex systems is a reality in almost all electronic application areas. Recent advances in microelectronics make possible the appearance of innovative solutions for several problems of the modern world, due to the creation in accelerated rhythm of quality digital systems, allowing the integration of tens of millions of transistors in a single chip with low operational cost. Those systems are in constant evolution promoted by the development of the semiconductors industry. Thus, there are strong pressures from the market to make new products available with an increasing number of functionalities. Implementations of complex electronic circuits must use of efficient and automated verification methodologies, which help in reducing design failures. In this context VeriSC, a functional verification methodology which provides testbenches and uses the SCV Library (SystemC Verification Library), but it is restricted to the digital circuit verification that has only synchronous time transactions. This work consists in creating a mechanism for the implementation of time transactions, applied to the VeriSC functional verification methodology, and in making it an efficient methodology for digital circuits capable of processing asynchronous time transactions.
