The verification of digital sub-systems is based on advanced techniques such as constraints capture, randomized or pseudo-randomized stimuli generation and results collection with functional coverage evaluation. The use of manually verified hand-coded analog block models within a digital verification environment has so far been sufficient. However, the move to greater levels of integration, shrinking process […]
More than 50% of highly complex systems-on-chip (SoCs) have functional issues at first silicon, issues that emerge after engineers have spent much time and money on verification and emulation. These issues delay time-to-ramp and cause significant losses of direct and indirect product revenue. All this demonstrates the need for efficient post-silicon debug methodologies and tools. […]
The ‘state-of-the-art’ solution for wireless transceiver RF ICs is single chip CMOS, integrating digital, analog, and RF blocks on a single chip. The architectures involved require new and challenging approaches to verification. To understand these, we first need to look back at the history of the transceiver architectures used for wireless mobile phone implementations during […]
Ellen Sentovich As EDA Tech Forum went to press, the programme for 2006’s Design Automation Conference (July 24-28) in San Francisco was only just being made public. However, one thing was already clear. The event is set to be bigger than ever before. “We had been concerned about the move to July because of the […]
Why are more chips late to market and cost three times more to design at 90-nanometer (nm) than at 130nm? Today’s ASSPs and ASICs are huge, approaching one billion transistors, with clock speeds exceeding 1-GHz. Engineers struggle to manage the complexity of devices that achieve these levels of performance and size. A natural reaction to […]
When migrating from FPGA prototype to ASIC, engineers need to interface with multiple silicon and software vendors. Designing with FPGAs often requires the use of several software platforms, including front-end synthesis tools, FPGA software development tools, and verification and timing analysis tools. Migrating to an ASIC platform involves using a parallel design flow with different […]
Productivity levels for hardware design, specification, simulation and validation have been raised by the formal approval of IEEE 1800 SystemVerilog as an industry standard. Evolved from the Verilog hardware description language, SystemVerilog is now the language of choice for developing verification and design intellectual property (IP). As a result, EDA companies are progressing rapidly in […]
Designers thinking about low power and energy have a variety of strategies at their disposal. The most common are: Process/libraries (e.g. low-power processes/libraries; high and low threshold voltage cells; and voltage scaling); Power and voltage domains; Clock gating; Low-power optimized clock synthesis; Low-power synthesis (e.g. automatic insertion of operand isolation circuitry); Implementation optimizations (e.g. operand […]
Slowly but surely, the doors are opening. By that I mean that foundries and some IDMs are finally releasing significant amounts of fab process data for incorporation within the design for manufacturing content of EDA tools. Kudos must go to the IBM, Samsung and Chartered Semiconductor Manufacturing triumvirate for being first out of the gate. […]
As the third wave of the digital revolution finally gains momentum, the chip industry is breaking loose from its homogeneous telecom/PC-centric confines – where everyone’s product and box essentially looked and worked the same – into the arms of the fragmented consumer-centric heterogeneous multimedia, with significantly more brand names and lots of different price points.
