Semiconductor Manufacturing International Corporation (“SMIC”, NYSE: SMI and SEHK: 0981.HK), one of the leading foundries in the world, and Ansoft Corporation (Nasdaq: ANST) announced immediate availability of the industry’s first parameterized spiral inductor design kit based on full-wave simulation. The kit enables RF CMOS designers to create and simulate custom inductor geometries by directly linking Ansoft’s HFSS and SMIC’s CMOS process parameters.
The spiral inductor kit is built upon SMIC’s Electromagnetic Design Methodology (EMDM) — which allows engineers to easily and accurately create any RF structure — and gives designers the flexibility to innovate new geometries simply by editing parameters such as diameter, number of turns, width and spacing of traces from a dialog box in HFSS. Included in the kit are ready-to-solve, fully parameterized HFSS projects for circular, square, hexagonal, and octagonal coils in the regular, stacked, transformer, and balanced configurations with all vias and underpasses included.
“Spiral inductors with small form factors, high Q, and high self-resonant frequencies are highly desired to meet the need for greater portability, increased functionality, and lower costs for today’s communication systems,” said Dr. Lee Yang, head of RF Application and Design Support in Marketing of SMIC. “Our collaboration with Ansoft allows our customers to design, simulate, and optimize spiral inductors on silicon substrates, relieving a major bottleneck of the RF CMOS design flow. Furthermore, we encouraged Ansoft to provide a path to back annotate to backend layout tools, making it very practical to innovate new designs and pass the results to standard layout tools.”
“SMIC continues to prove to be an excellent partner for Ansoft as it is taking a leadership position in terms of addressing RF designer requirements,” said Jack Qiu, Country Manager of China People Republic at Ansoft. “Early on, SMIC recognized the advantages of offering accurate electrical models for on-chip passive components and worked with Ansoft to create a methodology to streamline the process of incorporating the additional accuracy provided directly in circuit simulation. Using EMDM along with the new spiral inductor design kit, customers can now compute the inductance and quality factor (Q) for spiral inductors, rapidly develop a custom library for their own requirements including proximity effects, and utilize them directly in circuit and system simulation. EMDM makes it practical to synthesize entirely new inductors and rapidly back annotate this information into circuit schematics and standard layout tools.”
