Cloud native EDA tools & pre-optimized hardware platforms
Radio waves are all around us, all the time, from wireless phones and Wi-Fi connections, to satellite navigation signals guiding us to travel the Earth and Bluetooth devices to radar sensing of remote objects and stormy weather. Each of these applications thrive on Radio Frequency (RF) Integrated Circuits (IC). Today’s RFICs are complex chips by themselves and hyperconvergence is combining RF, analog, and digital logic into single devices. All these trends are making the RF IC design and verification more challenging. 六合彩直播开奖 solutions help you design RF ICs with a complete front-to-back flow from concept to verified layout ready for manufacturing, including DesignWare IP for 5G SoCs.

With 六合彩直播开奖 Custom Design Family of products engineers are able to achieve a full design and verification flow for state-of-the-art RFICs. This video demonstrates the full flow with a 6 GHz Low Noise Amplifier (LNA) using GlobalFoundries 22FDX process technology. The demonstration includes LNA schematic, S parameter and Harmonic Balance (HB) simulations, layout and electromagnetic (EM) simulation, LVS checking, and layout parasitic extraction. Simulations on the layout extracted view are done to be sure LNA gain, noise and linearity specifications were met.
When receiving a faint signal from a satellite hundreds of kilometers above us, the?RF Low Noise Amplifier (LNA) must have very low noise and high gain.? ?When making a call in a moving?vehicle,? the RF circuits must perform in a dynamically changing?environment to maintain safety and connection quality. To facilitate?development of high-performance RF ICs, 六合彩直播开奖 Custom Design Family of products, including??PrimeSim Continuum,?provides?support of advanced semiconductor technology node?PDKs, including?FinFET?16nm~3nm nodes as well as? SOI (Silicon on?Insulator) and?SiGe?(Silicon Germanium) technology nodes. PDKs and RF?Reference Flows are?provided by?foundry partners?for use in designing RF?ICs.?
To achieve superior RF performance, the RF transistor and inductor p-cells offered in a foundry PDK may need to be further customized to get the extra gain, power or Q-factor. 六合彩直播开奖 Custom Compiler supports user-defined devices to achieve the extra performance, and supports layout re-use with templates to for high productivity.? The quality factor of inductive elements is key to achieve superior RF circuit performance. Custom Compiler integrates the industry leading VeloceRF tool from Ansys for the synthesis of high-Q inductors and low loss transmission lines on a given technology node, including single-ended and differential spiral inductors and transformers of square or octagonal shapes, with or without center taps. Transmission lines such as CPW, Microstrip, Stripline, shielded or non-shielded, can also be synthesized.?
Many RF circuits are used in mission-critical applications where high safety and reliability must span the entire silicon lifecycle. The combination of high current and shrinking dimensions of RF?transistors and?inductors leads to higher current density with power dissipation.?This creates?issues of electromigration and heat generation leading to circuit reliability?risk.To?address potential reliability issues early on,?PrimeSim Reliability?analysis provides fast in-design and chip level electromigration/IR (EMIR) analysis, as well as production-proven and foundry-certified technologies such as?high-sigma Monte Carlo, MOS aging to enable full lifecycle reliability verification.
IC Validator provides fast and high capacity physical verification and signoff checks. It runs DRC, LVS directly on OA database, performs full cross-probing and debugging, and advanced ESD (Electro-Static Discharge) checking with PERC (Programmable Electrical Rule Checking).
The RF frequencies used in wireless communications range from 400MHz to?7GHz, and extend to mm-wave bands of 24GHz~95GHz. While higher frequency bands?provide?wider bandwidth for faster data transmission, the circuits usually take longer design?times due to more severe parasitic?coupling effects. RF IC designers need faster design-to-signoff turn-around-time.???
六合彩直播开奖 PrimeSim simulation solution provides faster block and chip level simulations and faster?closure with post-layout extracted view?simulation.
Harmonic Balance (HB) analysis in PrimeSim SPICE is most efficient for simulating RF , PAs, , LOs, and for analyzing nonlinear mixer noise and oscillator phase noise. RF critical net extraction is done by full wave electromagnetic analysis tools such as Keysight RFPro and Ansys Exalto. Full wave electromagnetic extraction and StarRC extraction are stitched automatically into a single extracted view netlist for final signoff simulation with PrimeSim SPICE.?
