In an electronic world driven by smaller devices packed with larger functions, power becomes a critical factor to manage. With power consumption leading to heat dissipation issues, reliability of the device can be affected, if not controlled or the device not cooled. Moreover, for mobile devices such as smartphones or tablets… Read More

CDC Verification: A Must for IP and SoCs
In the modern SoC era, verification is no longer a post-design activity. The verification strategy must be planned much earlier in the design cycle; otherwise the verification closure can become a never ending problem. Moreover, verification which appears to be complete may actually be incomplete because of undetected issues… Read More
Physically Aware DFT Improves PPA
Introducing on-chip test circuitry has become a necessary criteria for an ASIC’s post manufacture testability. The test circuitry is usually referred as DFT (Design-for-Test) circuit. A typical methodology for introducing DFT circuit in a design is to replace usual flip-flops with special types of flip-flops called ‘scan… Read More
Writing the unwritten rules with ALINT-PRO-CDC
EDA verification tools generally do a great job of analyzing the written rules in digital design. Clock domain crossings (CDCs) are more like those unwritten rules in baseball; whether or not you have a problem remains indefinite until later, when retaliation can come swiftly out of nowhere.
Rarely as overt or dramatic as a bench-clearing… Read More
Expert Tool to Easily Debug RTL and Reuse in SoCs
SoC design these days has become a complex and tricky phenomenon involving integration of multiple IPs and legacy RTL code which could be in different languages, sourced from various third parties across the globe. Understanding and reusing RTL code is imperative in SoC integration which needs capable tools that can accommodate… Read More
A Complete Scalable Solution for IP Signoff
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
A Complete Timing Constraints Solution – Creation to Signoff
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
SpyGlass CDC: A Comprehensive solution for addressing CDC issues
About a decade ago, semiconductor designs had just a few asynchronous clocks which were easily managed by designers through the process of manual design reviews. The situation today is completely different. An SoC can have hundreds of asynchronous clocks, driving different complex functions, spread across various IPs, supplied… Read More
RTL Designers Can Win a GoPro Camera at DAC
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
Expert Constraint Management Leads to Productivity & Faster Convergence
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
