Andes Technology and Mirabilis Design Announce Collaboration on System-Level Models for Andes RISC-V Processor IP

Validated Architecture Models Enable Early Design Exploration and Pre-RTL Optimization

Hsinchu, Taiwan / Santa Clara, CA – July 27, 2026 – Andes Technology, a leading supplier of high-performance, energy-efficient RISC-V processor IP and a Founding Premier Member of RISC-V International, and Mirabilis Design today announced a strategic collaboration to deliver system-level architecture models for Andes RISC-V processors. This partnership empowers SoC architects to evaluate and optimize processor-based designs well before RTL development.

As part of this collaboration, Mirabilis Design has developed and validated system-level models for the Andes AX66 multicore and Andes A45 processors using the VisualSim® platform. The models allow architects to explore performance, power, and system behavior early in the design cycle, significantly reducing iteration time and architectural risk.

Parameterized Architecture Exploration Without Model Modification

The Andes system-level models support scalable multicore clusters, connected through AMBA AXI-based interconnects, with options for coherent cache hierarchies. Architectural exploration is performed entirely through parameter settings defined in the processor specifications, including:

• Number of cores per cluster and number of clusters
• Core configuration options
• Cache size, hierarchy levels, and coherency
• System address map and memory partitioning across multiple DRAMs

Users do not need to modify the model implementation. Design-space exploration is achieved by adjusting parameters, enabling rapid and repeatable evaluation of alternative configurations.

• RVA23, Multi-cluster, Hypervisor and Android
• 32-bit 8-stage superscalar processor that supports RISC-V specification, including GCNP and Linux

Software-Aware System Analysis

The models support execution of software traces and benchmarks, including workload distribution across multiple cores within a cluster. This capability allows architects to analyze their system-level performance impact early and align hardware configuration with software requirements.

This approach enables architects to tune processor topology, cache organization, and memory structure before RTL integration, improving predictability and reducing downstream design changes.

Industry Quotes

“Early architectural decisions are critical to achieving SoC optimal performance and efficiency,” said Dr. Charlie Su, President and CTO, Andes Technology. “This collaboration enables our customers to evaluate Andes RISC-V processor configurations at the system level and finalize specifications with greater confidence before implementation.”

“System-level modeling allows SoC architects to explore processor, cache, and memory trade-offs using real software behavior,” said Deepak Shankar, Founder, Mirabilis Design. “Our validated models of Andes AX66 and A45 processors support fast, parameter-driven exploration without requiring model rewrites.”

Availability and Roadmap

The Andes system-level processor models are available as part of the VisualSim® platform. Additional Andes RISC-V IP and configurations will be added over time to extend coverage across applications and markets.
