Is There Any Hope For Asynchronous Design?

By Brian Bailey - 25 Apr, 2024 - Comments: 6

In an era when power has become a fundamental design constraint, questions persist about whether asynchronous logic has a role to play. It is a design style said to have significant benefits and yet has never resulted in more than a few experiments. Synchronous design utilizes a clock, where the clock frequency is set by the longest and slowest path in the design. That includes potential var... » read more

Implementation Of An Asynchronous Bundled-Data Router For A GALS NoC In The Context Of A VSoC

By Fraunhofer IIS/EAS - 09 May, 2018 - Comments: 0

Designs of asynchronous networks-on-chip are of growing interest because a complete asynchronous implemen- tation can solve the synchronization problems of large networks. However, asynchronous circuits suffer from the lack of proper design flows because their functionality often relies on timing constraints, which are not extensively supported by common CAD synthesis tools. This paper proposes... » read more

Respecting Reset

By Brian Bailey - 25 May, 2017 - Comments: 0

Resets are a necessary part of all synchronous designs because they allow them to be brought into a known state. However, such a simple process can lead to many problems within an [getkc id="81" kc_name="SoC"]. No longer can reset be considered a simple operation when power initially is applied to a circuit. Instead, the design of reset has many implications on cost, area and routability, a... » read more

Asynchronous’ Impact On Tools

By Ann Mutschler - 25 Jun, 2015 - Comments: 0

In the right situation, using asynchronous logic makes a lot of sense—especially for security and IoT. But moving into the asynchronous design involves making tradeoffs, figuring out how the technical requirements of an application will impact the design, and understanding the limits of EDA tools in this area. “It's going to be halfway between digital and analog support,” said Bernard ... » read more

Asynchronous Design: Is It Time Yet?

By Barry Pangrle - 05 Jun, 2015 - Comments: 0

Non-mainstream technologies can offer advantages over more commonly used approaches, but usually at some additional cost (otherwise they’d probably be mainstream). The additional cost could be in design time, area, testability or whatever, and it might even be only a temporary disadvantage. If comparable time and energy were invested in the new technology, perhaps the additional costs would d... » read more
