Simulation software aids optoelectronics
design
Software links with new hardware to enable up to 20 times faster electromagnetic simulation of optoelectronic devices such as CMOS image sensors.
Acceleware Corp and Synopsys have developed a new hardware solution that enables up to 20 times faster electromagnetic simulation of optoelectronic devices such as CMOS image sensors The solution, which links Synopsys' technology leading TCAD Sentaurus device simulation software and Acceleware's ClusterInABox Quad Q30 workstation, enables an order of magnitude speed up of the high accuracy finite difference time domain (FDTD) electromagnetic modelling algorithm used in Sentaurus Device

Synopsys has extended its PrimeTime static timing analysis product to address the challenge of detecting and resolving crosstalk on SoC designs at 0.18 micron and below.
Tensilica standardises on Physical Compiler
Tensilica has standardised on Synopsys Physical Compiler and developed a high-performance reference flow around Physical Compiler for its Xtensa V processor cores.
This performance increase allows engineers to leverage the rigour and accuracy of the FDTD method in designing and optimising optoelectronic devices while shortening the product development cycle.
In the rapidly growing optoelectronics market, manufacturers are under constant pressure to produce higher performance devices in a shorter time.
For example, CMOS image sensors, which are used widely in camera phones, webcams, digital cameras, and camcorders, have to pack more pixels into each device generation, as well as be cost effective to produce.

TCAD tools are well suited for optoelectronics manufacturers designing more sophisticated devices and performing complete characterisation of their device structures over a wide range of light incidence angles, lens shapes, pixel sizes, and other factors prior to manufacturing.
This high performance, cost effective solution also allows the statistical analysis of the impact of manufacturing variations, such as lens misalignment, through multiple simulations.
Due to the complex nature of optoelectronic devices, FDTD simulations typically require tens of hours to fully characterise a CMOS image sensor design in 3D.
The new hardware acceleration solution reduces the FDTD simulation time by up to 20 times, allowing engineers to carry out more extensive simulation studies, reducing development costs and time.
TCAD Sentaurus device simulation software uses the ClusterInABox Quad Q30's built in Nvidia graphics processing units (GPUs), which deliver up to two Teraflops of computational power, to significantly accelerate FDTD simulations of optoelectronic devices.
"The collaboration between Synopsys and Acceleware brings powerful TCAD simulation capabilities to our mutual customers, who are constantly looking for ways to reduce costs and time in developing advanced semiconductor devices", says Terry Ma, Group Director, TCAD business unit at Synopsys.
"Customers can now take advantage of this combined software and hardware solution to explore more design options and to optimise performance, manufacturability and yield for these complex optoelectronics device structures".
"Process and device engineers are continuously challenged with improving product performance in a shorter development cycle", says Ryan Schneider, Acceleware's Chief Technology Officer.
"Our deskside supercomputing solutions provide the fastest FDTD processing on the market, opening up new possibilities in innovation and product delivery for engineers working with Synopsys' sophisticated TCAD solution".
"The end result for manufacturers of optoelectronic devices is the ability to deliver higher quality products to their customers more quickly, without raising costs".
The Synopsys interface, TCAD Sentaurus Device EMW-X, is now available through TCAD Sentaurus Device EMW.
The ClusterInABox Quad Q30 workstation is available for purchase directly from Acceleware.
