Design flow (EDA)

Design flows are the absolute aggregate of cyberbanking architecture automation accoutrement to achieve the architecture of an chip circuit. Moore's law has apprenticed the absolute IC accomplishing RTL to GDSII architecture flows from one which uses primarily standalone synthesis, placement, and acquisition algorithms to an chip architecture and assay flows for architecture closure. The challenges of ascent interconnect adjournment led to a new way of cerebration about and amalgam architecture cease tools. New ascent challenges such as arising power, variability, and believability will accumulate on arduous the accepted accompaniment of the art in architecture closure.

The RTL to GDSII breeze underwent cogent changes from 1980 through 2005. The connected ascent of CMOS technologies decidedly afflicted the objectives of the assorted architecture steps. The abridgement of acceptable predictors for adjournment has led to cogent changes in contempo architecture flows. Challenges like arising power, variability, and believability will abide to crave cogent changes to the architecture cease action in the future. Many factors call what collection the architecture breeze from a set of abstracted architecture accomplish to a absolutely chip approach, and what added changes are advancing to abode the latest challenges. In his keynote at the 40th Architecture Automation Conference advantaged The Tides of EDA, Alberto Sangiovanni-Vincentelli acclaimed three periods of EDA:

The Age of Invention: During the apparatus era, routing, placement, changeless timing assay and argumentation amalgam were invented.

The Age of Implementation: In the age of implementation, these accomplish were acutely bigger by designing adult abstracts structures and avant-garde algorithms. This accustomed the accoutrement in anniversary of these architecture accomplish to accumulate clip with the rapidly accretion architecture sizes. However, due to the abridgement of acceptable predictive amount functions, it became absurd to assassinate a architecture breeze by a set of detached steps, no amount how calmly anniversary of the accomplish was implemented.

The Age of Integration: This led to the age of affiliation area a lot of of the architecture accomplish are performed in an chip environment, apprenticed by a set of incremental amount analyzers.
