Virtual Verification Of Computational Storage Devices


Over recent years, there has been a move to replace hard-disk drive (HDD) storage with solid-state drive (SSD) storage. SDDs are faster, contain no moving parts that can fail or be affected by environmental hazards, and the cost of SSDs has been dropping each year. Unfortunately, the verification of an SSD is quite complex. In particular because of hyperscale datacenter enterprise and client-dr... » read more

Lower Process Nodes Drive Timing Signoff Software Evolution


A dramatic rise in design complexity has led to a slew of new signoff challenges that impact the ability to predictably meet PPA targets. Smaller technology nodes and larger design sizes have caused the number of corners and modes to grow exponentially leading to much longer turnaround times for timing signoff. Moreover, larger design sizes demand huge compute resources for timing signoff. I... » read more

Clarifying Language/Methodology Confusion


Engineers working on modern, large FPGA designs face multiple challenges: changing languages, methodologies and tools implementing them. The fact that many designs now contain both hardware and software only add to the confusion. This document tries to clarify the situation. Click here to read more. » read more

Rigid-Flex PCB Bending EM Analysis Using Clarity 3D Solver


Rigid-Flex PCBs have been used in many modern electronic devices (such as mobile phones, laptops, and wearables, among others), due to their form factor, light weight, and cost-effectiveness. Electromagnetic (EM) analysis of Rigid-Flex PCBs has always been a challenging task for many commercially available 3D numerical solver technologies (FEM and FDTD), due to the complexity in the 3D designs.... » read more

Side Wettable Flanks For Leadless Automotive Packaging


The MicroLeadFrame (MLF)/Quad Flat No-Lead (QFN) packaging solution is extremely popular in the semiconductor industry. It is used in applications ranging from consumer electronics and communications to those requiring high reliability performance, such as the automotive industry. The wide acceptance of this packaging design is primarily due to its flexible form factors, size, scalability and t... » read more

Impact Of EUV Resist Thickness On Local Critical Dimension Uniformities For <30nm CD Via Patterning


This paper describes the impact of extreme ultraviolet (EUV) resist thickness on <30 nm via local critical dimension uniformity (LCDU) measured during after development inspection (ADI) and after etch inspection (AEI). For the same post-etch CD targets, increasing resist thickness from 40 to 60 nm helped reduced CD variability. This work was performed via virtual fabrication using Coventor�... » read more

SystemVerilog Constraints


This paper looks at two of the most common issues when constraint solver results do not match your intent: Not understanding how Verilog expression evaluation rules apply to interpret the rules of basic algebra and not understanding the affect probability has on choosing solution values. Coding recommendations for improving your code to get better results are provided. To read more, click here. » read more

Maximizing Ansys LS-DYNA Performance With AMD EPYC 7Fx2 Processors


AMD EPYC 7Fx2 processors bring high frequencies and very highs ratios of cache per core to the 2nd Gen EPYC family of processors. EPYC 7Fx2 processors build on the large memory capacity, extreme memory bandwidth and massive I/O of the 2nd Gen EPYC family to deliver exceptional HPC workload performance. This paper describes the excellent performance of these chips in running Ansys LS-DYNA comput... » read more

IP Security Assurance Standard


This whitepaper is available from the IP Security Assurance (IPSA) Working Group that describes Accellera’s initial proposal to address the industry’s security concerns involving IP integration. Since integrators typically treat IP as a “black box,” vulnerabilities may inadvertently be inserted into an SoC/ASIC. The whitepaper details the objectives of the IPSA standard and its approach... » read more
