Lightweight formal verification platform
IBM is offering RuleBase Single-Thread Edition (SE), a lightweight version of its RuleBase formal verification platform as an entry-level product for those looking for a small scale solution.
The high programmability of the DC/DC IP core output voltage gives SoC integrators full flexibility to optimise system performance.
The IP core achieves a high level of integration including internal references, internal regulators and system power-on-reset to enable a "plug-and-play" power management functionality.
The IP core comes with a fully functional Verilog behaviour model to ease integration and system verification.
"As part of the industry's most comprehensive offerings in power management IP, our step-down DC/DC convertor IP provides SoC designers with the ability to overcome some of their most vexing challenges for system integration", says Nuno Ramalho, Vice President of Audio and Power Solutions for Chipidea.
"This core's highly integrated functionality addresses such design issues as the generation, observation and management of multiple voltage domains".
"This in turn lets SoC engineers focus on the key differentiating characteristics of their chips and helps them speed time to market".
The latest core is part of the CI2512 step-down DC/DC convertor IP family that is available in TSMC 130 and 90nm process technologies.
In addition, Chipidea offers the CI2522 step-down DC/DC convertor IP family, a fully integrated, low pin count solution in SMIC 130nm process technology.
Both offerings will soon be available in other top-tier semiconductor foundries.
The wide availability of these IP families in several technologies provides IDM and ASIC vendors, fabless IC and ASSP providers, start-up companies and fabs with the flexibility to address their device scaling and porting strategies.
Chipidea's catalog of power management solutions cover a wide range of applications and offers enhanced levels of programmability for SoC designers.
Available at several foundries and in many process technologies, this catalog includes switched regulators, charge pumps, linear regulators, power-on-reset circuits, oscillators, reference generators, battery chargers for main and backup batteries, and complete power management units.
