Block-Level Simulation

Cadence^® custom simulation technology delivers all the tools required for designing and verifying your analog/mixed-signal blocks. Simulating blocks has evolved since the days of op-amps and comparators. Consider a typical block such as a fractional-N PLL that has more devices than some traditional analog chips. For block-level design, the steady-state analysis provided by the Spectre^® platform can be invaluable for evaluating the noise and transfer functions of blocks like dynamic comparators, time-to-digital converters, et cetera. Block-level verification includes long transient simulations to calibrate blocks, for example, VCO calibration. For blocks, transistor-level simulation is used for verification and it may require transient noise analysis to simulate the key parameters like phase noise.

Chip-Level Simulation

Leveraging custom design abstraction capabilities, Cadence chip-level simulation looks at all the blocks abstracted into a variety of languages combined with transistor-level blocks that converge on a whole design understanding. Cadence chip-level simulation solutions provide the large capacity and high performance required to ensure that a full chip is working as intended, regardless of how the blocks perform in aggregate.

Memory Simulation

The combination of an accurate FastSPICE solver with new internal statistical analysis features for high-sigma analysis makes quick work of designing and verifying your advanced-node SRAM, DRAM, and NAND flash memory designs.

Mixed-Signal Simulation

Today’s system-on-chip (SoC) designs integrate complex analog and digital blocks, requiring thorough testing and analysis of how analog and digital circuits interact and the influence they have on each other. Cadence mixed-signal simulation solution combines the industry-leading digital and analog circuit simulators: Xcelium^TM and Spectre, to provide designers and verification engineers superior performance and accuracy required for today’s designs.

With the Spectre platform, you have tools with a common infrastructure, advanced simulation database, versatile front-end parser, and a robust device library. Through integration with our Virtuoso^®, Allegro^®, and Innovus^TM solutions, the Spectre tools deliver comprehensive design and verification.

RF Simulation

As the boundaries between IC and systems designs fade, RF components have increasingly become part of the standard chip mix of ICs.  The Cadence RF simulation solution contains a wide range of analyses, provides design insight and enables verification of broad RFIC types,  including mixers, transceivers, power amplifiers, dividers, switched capacitors, filters, and phase-locked loops (PLLs). It also supports extensive noise, distortion analysis technologies, and application-centric analysis, such as wireless analysis for system-level performance evaluation using standard-compliant signal sources.
