“We have fully incorporated PathWave ADS into our RFIC design flow, whether using GoldenGate and RFPro within the Cadence Virtuoso environment or stand-alone within ADS. The stand-out tool for us has been RFPro, which has resulted in significant time and cost savings while providing highly accurate results comparable to other on-chip and traditional EM simulators. The ability to EM simulate complete RF blocks and automatically generate fully back-annotated schematics has given us an extra level of confidence heading into each new design. RFPro has been instrumental to several first pass success chips at TeraDAR, which in turn has saved us five-to-six months in re-design and fabrication time.”

“PathWave ADS and RFPro give us an end-to-end design and simulation solution for our micro-electro-mechanical systems (MEMS) module workflows. We rely on the PathWave ADS workflow to automate the development of our MEMS products from device wafer level to module integration with other components, as well as PCB design including MEMS device or module plus RF connectors. SmartMount makes integration of different technologies, such as flip-chip or wire bond, onto the module substrate and the PCB board as simple as stacking LEGO blocks. RFPro makes 3D model generation, including complicated MEMS devices, much quicker for our EM analysis.”

“Thanks to the new A-LFNA (E4727B), we are able to collect data with a large number of time steps. This is a great help to distinguish and visualize the RTN signal automatically. The total modeling efficiency is improved 10X. And in terms of long-term prediction, the model accuracy is much better than before.”

“The thing we really like about Keysight is the ecosystem. You can have VSA software running on an oscilloscope or spectrum analyzer along with IQ tools running on a Keysight AWG. Keysight really provided an end-to-end solution with a common platform and excellent technical support for simulation and measurement.”

“ADS Harmonic Balance gives us trustworthy simulations before committing to fabrication. We can estimate the influence of each parameter over the global circuit response, tuning and optimizing the circuit before committing to fabrication.

“MBP is the most efficient tool I have used for device modeling. It supports the Verilog-A model well, and the parameters are easy to extract using MBP’s optimizers and automated model extraction flows. Because of these capabilities, MBP is a tremendous help in my work.”

“In our study, we needed to capture the network parameters of FinFET devices from kHz to several GHz. IC-CAP controls the entire measurement system and intuitively displays the measurement data on a graphical interface. The parameter extraction procedure was realized through PEL/Python programming. The calling ADS simulator function, as well as the built-in optimizers in IC-CAP, were effective in ensuring accurate model simulation results and highly efficient model generation.”
