Cadence

Cadence posted Mixed-Signal Systems and Verification Engineer R55855. The assigned work develops accurate, simulation-efficient SystemVerilog analog/RF behavioral models, verifies them against analog schematics, integrates them with RTL, and checks analog functionality against specifications using testbenches, scenarios and assertions. Qualifications name RNM, UDN/UDT/UDR, wreal, Verilog-AMS and analog assertion-based verification. Modeling and verification results are documented for formal review. This records an engineering hiring mandate rather than a product release or a reported customer deployment.

FMCAD paper reports SMT-based formal verification of SystemVerilog RNM

TU Wien's repository made available Augusto Mafra and Haniel Barbosa's FMCAD paper on formal verification of SystemVerilog RNM by extending Yosys and Pono. The study uses 31 benchmarks: 17 public GPL-3.0 benchmarks and 14 built from proprietary Cadence models/testbenches. It compares real-arithmetic and IEEE floating-point SMT interpretations, whose semantics can produce different verification results. The v2.0.5 public implementation provides benchmarks, results and fixed revisions of Yosys, Pono and smt-switch. This is a research flow, not a claimed Jasper product feature; September 2 dates the paper's repository availability.

Cadence blog introduces Verilog-A tutorials for analog circuit blocks

A Cadence official blog introduces Verilog-A teaching material for circuit and functional blocks, including ADCs, DACs, operational transconductance amplifiers, phase detectors and signal sources. It discusses Laplace- and Z-transform modeling for transfer functions. The Event dates the blog introduction, not the initial publication of every linked video, and is limited to circuit-block modeling rather than the device examples also mentioned in the article.

Cadence author applies metamorphic testing to a SystemVerilog RNM receiver model

A Cadence DVCon U.S. 2026 paper applies metamorphic testing to a SystemVerilog real-number model of a receiver baseband, ADC, and automatic-gain-control system where a detailed test oracle is impractical. It defines relations for doubled or halved input, constant ADC magnitude, and plus-or-minus 6 dB RSSI changes and exercises them with randomized stimuli. This is a reported case study, not an AI method or a company-wide deployment claim.
