Making Software Development Equivalent For Models And Boards


Selected Cortex-M processors include the instruction trace microcell (ITM) to help understand system behavior. Although it can provide other types of trace, the ITM is commonly associated with printf() output and event tracing from applications and operating systems. Historically, Fast Model systems have used semihosting or UART models to provide character and file I/O when running software on ... » read more

Fast Models, Cycle Models


There has been a lot of coverage since the launch of new CPU and graphics cores at Computex 2017, including some information about early software development. The public announcement of new ARM IP is a milestone for ARM Models because it means we can now talk about available models and share additional information about the new IP. ARM Fast Models and Cycle Models enable virtual prototyping ... » read more

Verification Unification


Semiconductor Engineering brought together industry luminaries to initiate the discussion about the role that formal technologies will play with Portable Stimulus and how it may help to bring the two execution technologies closer together. Participating in this roundtable are Joe Hupcey, verification product technologist for [getentity id="22017" e_name="Mentor, a Siemens Business"]; Tom Fitzpa... » read more

Power/Performance Bits: June 13


Theoretical all-carbon circuits Engineers at the University of Texas at Dallas, the University of Illinois at Urbana-Champaign, the University of Central Florida, and Northwestern University designed a novel computing system made solely from carbon. "The concept brings together an assortment of existing nanoscale technologies and combines them in a new way," said Dr. Joseph S. Friedman, ass... » read more

Huawei Delivers Outstandingly Accurate Models


By John Parry, Mentor, a Siemens Business, and Yake Fang, Huawei Technologies Co., Ltd. Packaging high-performance multi-core IC devices used in communication applications is a key challenge for both manufacturers and system integrators. Traditionally a System-in-Package (SiP) has been taken, with chips mounted side-by-side, allowing differing semiconductor technologies to be mixed. More r... » read more

Bringing Advanced Semiconductor Manufacturing Technologies To Higher Education


Universities and other institutions of higher learning play a key role in developing our next generation of semiconductor technologies. Along with the theory of semiconductor technology, our next generation of scientists and engineers must learn about the practical methods used to design and manufacture the latest generation of semiconductor products. Recently, Coventor’s predictive, 3D proce... » read more

Creating An Accurate FEOL CMP Model


By Ruben Ghulghazaryan, Jeff Wilson, and Ahmed AbouZeid For decades, semiconductor manufacturers have used chemical-mechanical polishing (CMP) as the primary technique for the smoothing and leveling (planarization) of dielectrics and metal layers. CMP modeling allows  design and manufacturing teams to find and fix potential planarization issues before the actual CMP process is applied to a ... » read more

Cars, Security, And HW-SW Co-Design


Semiconductor Engineering sat down to discuss parallel hardware/software design with Johannes Stahl, director of product marketing, prototyping and FPGA, [getentity id="22035" e_name="Synopsys"]; [getperson id="11411" comment="Bill Neifert"], director of models technology, [getentity id="22186" comment="ARM"]; Hemant Kumar, director of ASIC design, Nvidia; and Scott Constable, senior member of ... » read more

Does Power Analysis Need To Be Accurate?


The mere mention of accuracy in power analysis and optimization today can trigger a contentious discussion, even among typically reserved engineers. What is needed and where? Which tools are truly as accurate as claimed? And how much accuracy is actually needed for power analysis, [getkc id="112" kc_name="estimation"], and optimization? First of all, the accuracy required really depends o... » read more

Models Are Dead? Long Live Models


During the first half of this year I had more discussions with customers on models again. Are models back? For what purpose? In short, it looks like models are well adopted and in use for software development. For performance and architecture analysis, however, as a recent presentation from Renesas at CDNLive Japan shows, users just use RTL as that accuracy is required. In combination with emul... » read more
