IEEE 1801: UPF achieves formal standardisation as IEEE-1801
Shrenik Mehta, chairman of Accellera observes, "Industry acceptance of the IEEE 1801 standard power format can help optimize the energy consumption of future electronic systems by enabling engineers and tools to characterize and improve semiconductor power usage much earlier in the design cycle." announced today that the IEEE has approved a new standard, IEEE 1801, "Standard for Design and Verification of Low Power Integrated Circuits." The standard is also known as Unified Power Format (UPF) 2.0, and engineers in many chip-design teams worldwide already employ it to convey aspects of an IC design that are critical to low-power specifications from one tool to another throughout an electronic system design, analysis, verification and implementation flow.
EDA Blog: The IEEE has approved a new IEEE 1801 standard for Design and Verification of Low Power Integrated Circuits. The standard is also known as Unified Power Format (UPF) 2.0. UPF (first developed by Accellera) and is currently supported by multiple vendors and is in use worldwide. This is the first time that UPF has undergone an IEEE standardization effort. The IEEE 1801 standard provides portability of low-power design specifications that can be used with a variety of commercial products throughout an electronic system design, analysis, verification and implementation flow. Enhancements to UPF in the new standard include support for bias supplies (N-well, P-well, Deep-N-Well, and Deep-P-Well), greater flexibility and capabilities in specification of power states, and enhanced semantic capabilities for merged power domains.

Application engineers (EDN Blog)
Application engineers
Application engineers are the unsung heroes of EDA. They have to blend the technical skills of designers with the interpersonal skills of salespeople. Most AEs start out as design engineers (or software engineers for the embedded market). But not all design engineers make it as AEs, partially because, as I’m sure you’ve noticed, not all design engineers have good interpersonal skills! There’s also another problem, memorably described to me years ago by Devadas Varma: “they’ve only been in the restaurant before; now they’re in the kitchen they’re not so keen on what it takes to prepare the food.” Being an AE means cutting more corners than being a design engineer, and some people just don’t have that temperament. An AE usually has to produce a 95% solution quickly; a design engineer has to take whatever time it takes to produce a 100% solution.
AEs have a lot of options in their career path. As they become more senior and more experienced they have four main routes that they can take.

Oasys Design Systems- RealTime Designer - Multi-Million Gate RTL Synthesis

Introducing RealTime Designer (Connecting RTL to Silicon)
(Oasys Design Systems)
Oasys was founded in 2004 by a team of leading EDA developers, funded by successful entrepreneurs from the IC design and EDA business, with the intent of creating a new platform for IC implementation to address the 65 nanometer and below technology.
RealTime Designer operates at the RTL level and delivers stunning quality of results while doing it at speeds previously thought impossible and with a capacity of 100 million gates
Simply stated, RealTime Designer is a full chip, physical RTL synthesis product that provides a new platform for nanometer design delivering the following capabilities:
- 20X - 60x run time advantage over existing tools
- Best quality of results
- Chip scale capacity
- Plug and play with existing EDA flows
- Day one usability
- Dramatic reductions in P&R run times
- The best starting point for physical implementation
RealTime Designer follows a “Place First” methodology that takes the RTL, partitions it into blocks, places the RTL in the context of a floorplan and implements each block all the way to placement. Chip-level constraints are automatically propagated across the blocks and the design is optimized for the best possible quality of results. During the optimization phase, RealTime Designer will repartition the design at the RTL and re-implement until the chip-level constraints are met.
Design teams must manually check for many results, such as design congestion, and send the design repeatedly through synthesis and layout. RealTime Designer is the first product to automate that process. Designers can give RealTime Designer the chip floorplan as input or, if no floorplan exists then Oasys will create a floorplan including macro, pin and I/O placement. At completion RealTime Designer produces a placed design and a netlist that meets the constraints in the context of the desired floorplan.
Synthesizing a physical block using TSMC 65nm – 700k instances, 70 Macros, running at 600MHz, and a “golden” floorplan – RealTime Designer completed the task in just 20 minutes and achieving design closure after a single iteration in place and route. In the traditional approach on the same design, a single iteration of synthesis took 14 hours. Furthermore, it took 6 months of iterations to achieve the best result of -300ps Worst Negative Slack, and in the end was not able to achieve design closure.
Real Time Designer takes in standard inputs, including Verilog, standard timing and physical libraries, SDC timing constraints, and floorplan. VHDL will be available later this year. Output has been tested through all the popular place and route systems.
