Standards help our EDA and IP industry grow more quickly and with less CAD integration efforts, and IP-XACT is another one of those Accellera standards (1685-2009) that is coming of age, and enabling IP reuse for SoC design teams. Here at SemiWik, we’ve been writing about Defacto Technologies and their prominent use of IP-XACT… Read More
I read the semiconductor press, LinkedIn and social media (Twitter, Facebook) every morning along with an RSS feed that I setup, staying current on everything related to using EDA tools to make the task of SoC design a bit easier for design teams. A recent press release announced a tool called SoC Compiler, so my curiosity was piqued… Read More
In an SoC world driven by IP, where an SoC can have hundreds of IP (sourced not only from 3[SUP]rd[/SUP] party but also from internal business units which can have a lot of legacy) integrated together, it has become essential to have a comprehensive and standard method to verify and signoff the IP. Additionally, these checks must … Read More
With the unprecedented increase in semiconductor design size and complexity design teams are required to accommodate multiple design constraints such as multiple power domains for low power design, multiple modes of operation, many clocks running, and third party IPs with different SDCs. As a result timing closure has become… Read More
DACis just 33 days away and who wouldn’t want a cool GoPro camerato play with? Your manager will certainly want you to first check out what’s new at DAC if your job involves getting to RTL signoff on time and within budget. The creative folks at Atrenta have figured out how to attract us with the offer of winning a GoPro camera,… Read More
The SoC designs of today are much more complex than ever in terms of number of clocks, IPs, levels of hierarchies, several modes of operations, different types of validations and checks for growing number of constraints at various stages in the design flow. As a semiconductor design evolves through several stages from RTL to layout,… Read More
There is always a rush to converge a semiconductor design toward faster closure, amid increasing divergent trends of multiple IPs and high complexities of various functionalities on a single chip. Every design house struggles hard to evolve its customized design flows with several short paths patched up to fix issues, global… Read More
Timing exceptions are ways of guiding design tools, primarily synthesis and static timing analysis (STA), but these days also place & route and perhaps other tools. Most paths in a design go from one register to the next register. Both registers are on the same clock, and the design needs to ensure that the signal can make it from… Read More
There is a new book out from Springer. The subtitle is actually a better description that the title. The subtitle is A Practical Guide to Synopsys Design Constraints (SDC) but the title isConstraining Designs for Synthesis and Timing Analysis. The authors are Sridhar Gangadharan of Atrenta in San Jose and Sanjay Churiwala of Xilinx… Read More
Given today’s design requirements with respect to low power, there is increasing focus on the contribution to total power made by a design’s clock trees. The design decisions made by the front-end team to achieve high performance without wasting power must be conveyed to back-end team. This hand-off must be accurate… Read More
