Early Simulation Of Multi-Cycle Paths And False Paths
By Taruna Reddy - 24 Jun, 2021 - Comments: 0

Designing with synchronous clocks avoids metastability issues on clock domain crossings, but it presents its own challenges when multi-cycle and false paths are involved. A multi-cycle path (MCP) occurs when a logical function requires more than one clock cycle to produce a final, stable result. The designer must ensure that the destination register does not clock until the result is ready. Thi... » read more

Verilog HDL And Its Ancestors And Descendants
By Imperas - 23 Jun, 2021 - Comments: 0

This paper describes the history of the Verilog hardware description language (HDL), including its influential predecessors and successors. Since its creation in 1984 and first sale in 1985, Verilog has completely revolu- tionized the design of hardware. Verilog enabled the development and wide acceptance of logic synthesis. For large-scale digital logic design, previous schematic-based techniq... » read more

Synopsys' Manuel Mota shows how splitting SoCs into smaller dies for advanced packaging and using die-to-die interfaces to enable high bandwidth, low latency, and low power connectivity can benefit hyperscale data centers. Siemens EDA's Chris Spear explains the relationship between classes and objects in SystemVerilog with a handy visualization and notes the difference between SystemVerilog ... » read more

Debugging Point-to-Point Resistance Using Contribution By Layer In IC Validator PERC
By Synopsys - 23 Jun, 2021 - Comments: 0

PERC Point-to-point resistance (P2P resistance) functionality is a crucial EDA technology to enable complex P2P effective resistance measurement along ESD paths in automation for foundry qualified ESD/Latch-up checker or in-house custom checker. This technology is applied to the entire chip, block, and IP designs on cell or transistor level layout database. Since the ESD path count could grow t... » read more

Automotive U.S. electric truck manufacturer Lordstown Motors has an electric truck but after a large buyer fell through, it admitted it does not have any firm orders on its trucks, according to an AP story. The CEO and CFO resigned earlier this week. The electric car company Canoo announced its US manufacturing facility will be in Oklahoma. Cadence revealed its Tensilica FloatingPoint DSP (... » read more

Shifting Toward Data-Driven Chip Architectures
By Ed Sperling and Ann Mutschler - 16 Jun, 2021 - Comments: 0

An explosion in data is forcing chipmakers to rethink where to process data, which are the best types of processors and memories for different types of data, and how to structure, partition and prioritize the movement of raw and processed data. New chips from systems companies such as Google, Facebook, Alibaba, and IBM all incorporate this approach. So do those developed by vendors like Appl... » read more

Arm's Adrian Herrera explores the latest version of AMBA ATP Engine, an open-source implementation of the AMBA Adaptive Traffic Profiles (ATP) synthetic traffic framework specification, which adds the ability to program AMBA ATP traffic generation from Linux environments. Cadence's Paul McLellan finds out just how effective glitching chips is by delivering incorrect voltages and clock freque... » read more

Targeting Redundancy In ICs
By Brian Bailey - 14 Jun, 2021 - Comments: 0

Technology developed for one purpose is often applicable to other areas, but organizational silos can get in the way of capitalizing on it until there is a clear cost advantage. Consider memory. All memories are fabricated with spare rows and columns that are swapped in when a device fails manufacturing test. "This is a common method to increase the yield of a device, based on how much memor... » read more

Week In Review: Design, Low Power
