• Cerebrus. In July 2021, Cadence announced its machine learning-based Cerebrus chip explorer product to automatically optimize the Cadence digital design flow for specified power, performance, and area goals across multiple blocks. Cerebrus utilizes a reinforcement learning approach to increase efficiency each time the optimization process is repeated.[22][23]

Other Cadence RTL to GDS II tools: Conformal Equivalence Checker, Stratus High-Level Synthesis, Joules Power Analysis, Quantus RC Extraction, Modus AutomaticTest Pattern Generation.

• Perspec System Verifier. Perspec was announced in 2014, for defining and verifying system-level verification scenarios, and then creating test cases to verify the scenarios using constraint-solving technology.[27] In mid-2018, Cadence announced that Perspec supported the new Accellera Portable Test and Stimulus Standard (PSS) standard.[28]

• Palladium. In 2015, Cadence announced the Palladium Z1 Hardware emulation platform,[31] with over 100 million gates per hour compile speed, and greater than 1 MHz execution for billion-gate designs.[32] Cadence's Palladium emulator was originally from Cadence's Quickturn acquisition in 1998.[33] In 2021, Cadence announced Palladium Z2, claiming a 1.5X performance and 2X capacity improvement over the prior Palladium Z1, for more than 18 billion gate+ capacity. Additionally, Cadence claimed Palladium Z2 could compile 10 billion gates in under 10 hours.[34][35]
• Protium. The Protium FPGA prototyping platform was officially introduced in 2014.[36] In 2017, Cadence introduced the Protium S1 built on Xilinx Virtex UltraScale FPGAs.[37] In 2019, Protium X1 rack-based prototyping was introduced,[38] which Cadence claimed supported a 1.2 billion gate SoCs at around 5 MHz.[39] Palladium S1/X1 and Protium share a single compilation flow.[40] In 2021, Protium X2 was announced; Cadence claimed a 1.5X performance and 2X capacity improvement over Protium X1, and that Protium X2 could compile 10 billion gates in under 24 hours.[41][42]

Chip design IP targeting areas including memory/storage/high-performance interface protocols (USB or PCIe controllers and PHYs), Tensilica DSP processors for audio, vision, wireless modems, and convolutional neural nets. Tensilica DSP processors IP[43] include:
