All engineers can enhance their mixed-signal low-power structural verification productivity by learning while doing with a PIEA RAK (Power Intent Export Assistant Rapid Adoption Kit). They can verify the mixed-signal chip by a generating macromodel for their analog block automatically, and run it through Conformal Low Power (CLP) to perform a low power structural check.  

The power structure integrity of a mixed-signal, low-power block is verified via Conformal Low Power integrated into the Virtuoso Schematic Editor Power Intent Export Assistant (VSE-PIEA). Here is the flow.

Applying the flow iteratively from lower to higher levels can verify the power structure.

Cadence customers can learn more in a Rapid Adoption Kit (RAK) titled IC 6.1.5 Virtuoso Schematic Editor XL PIEA, Conformal Low Power: Mixed-Signal Low Power Structural Verification.

The RAK includes Rapid Adoption Kit with demo design (instructions are provided on how to setup the user environment). It Introduces the Power Intent Export Assistant (PIEA) feature that has been implemented in the Virtuoso IC615 release.  The power intent extracted is then verified by calling Conformal Low Power (CLP) inside the Virtuoso environment.

• Last Update: 11/15/2012.
• Validated with IC 6.1.5 and CLP 11.1

The RAK uses a sample test case to go through PIEA + CLP flow as follows:

• Setup for PIEA
• Perform power intent extraction
• CPF Import: It is recommended to Import macro CPF, as oppose to designing CPF for sub-blocks. If you choose to import design CPF files please make sure the design CPF file has power domain information for all the top level boundary ports
• Generate macro CPF and design CPF
• Perform low power verification by running CLP

It is also recommended to go through older RAKs as prerequisites.

• Conformal Low Power, RTL Compiler and Incisive: Low Power Verification for Beginners
• Conformal Low Power: CPF Macro Models
• Conformal Low Power and RTL Compiler: Low Power Verification for Advanced Users

There is no better way other than a self-help training kit -- (rapid adoption kit, or RAK) -- to demonstrate the Incisive Enterprise Simulator's IEEE 1801 / UPF low-power features and its usage. The features include:

• Unique SimVision debugging 
• Patent-pending power supply network visualization and debugging
• Tcl extensions for LP debugging
• Support for Liberty file power description
• Standby mode support
• Support for Verilog, VHDL, and mixed language
• Automatic understanding of complex feedthroughs
• Replay of initial blocks
• ‘x' corruption for integers and enumerated types
• Automatic understanding of loop variables
• Automatic support for analog interconnections

Mickey Rodriguez, AVS Staff Solutions Engineer has developed a low power UPF-based RAK, which is now available on Cadence Online Support for you to download.

• This rapid adoption kit illustrates Incisive Enterprise Simulator (IES) support for the IEEE 1801 power intent standard.

Hi all,

I need to develop a digital design/verification solution to compile,elaborate and simulate SV designs (basically a complex xrun wrapper). I am an experienced user of xrun and I have done a number of these wrappers over the years but this one is to be more of a tool, intented to be used Company-wise, so it needs to be very well thought and engineered.

It needs to be robust, simple and extensible. It needs to support multi-snapshot elaboration, run regressions on machine farms, collect coverage, create reports, etc.

I've been browsing the vast amount of documentation on XCELIUM and, although very good, I can't find any document which puts together all the pieces of what I am trying to achieve. I suppose I am more clear on the elaboration, compilation and simulation part but I am really lacking on the other areas like : LSF, regressions coverage, where does vManager fits in all this, etc.

I'd appreciate if someone can comment on whether there is a document which depicts how such a DV flow can be put together from scratch, or whether there is a kind of RAK with some example xrun wrapper.

Thanks

According to a review by the SUN DAY Campaign of data just released by the Federal Energy Regulatory Commission (FERC), within the past month, the agency has dramatically revised its three-year forecast for changes in the U.S. electrical generating capacity mix. Sharp declines are foreseen for fossil fuels and nuclear power while accompanied by even stronger growth in renewable energy (i.e., biomass, geothermal, hydropower, solar, wind) than earlier projected.

The Redford Center, a California-based non-profit co-founded in 2005 by Robert Redford and his son, James, announced that every morning, from April 15-22, 2019, the organization will post an episode a day of "Renewable Therapy for Climate Anxiety," a conversational mini-series featuring Filmmaker, James Redford, and Matthew Nordan, clean energy investor and managing partner at MNL Partners. In each two-minute installment, the pair explores questions that nag environmentalists when it comes to renewable energy. Watch the first episode below.

A close look at the evidence suggests that China has not been engaged in “debt-trap diplomacy” in the Pacific, at least not so far. Nonetheless, if future Chinese lending continues on a business-as-usual basis, serious problems of debt sustainability will arise, and concerns about quality and corruption are valid. By Jonathan Pryke HONOLULU (March 2, 2020)—In an atmosphere of heightened geostrategic competition, China’s Belt and Road Initiative (BRI) has raised questions about the risk of debt problems in less-developed countries. Such risks are especially worrying for the small and fragile economies of the Pacific.
