HSINCHU, Taiwan and SANTA CLARA, CA, July 29, 2026 – Andes Technology and Mirabilis Design have developed system-level architecture models for the Andes AX66 multicore and A45 RISC-V processors using the VisualSim platform. The models allow SoC architects to evaluate processor, cache, memory and interconnect configurations before RTL development.
Architecture Parameters
The models support multicore clusters connected through AMBA AXI-based interconnects, with options for coherent cache hierarchies. Architects can configure the models through processor parameters that cover:
- 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 can change these settings without modifying the model implementation. This allows engineering teams to compare different system configurations using the same underlying models.
Software Trace Analysis
The VisualSim models support software traces and benchmarks, including workload distribution across multiple cores within a cluster. Architects can use these workloads to examine system-level performance and compare hardware configurations with software requirements before RTL integration.
The analysis covers processor topology, cache organization and memory structure during the architecture stage. Mirabilis Design said it validated the system-level models for both Andes processors.
“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
The Andes processor models are available through the VisualSim platform. Mirabilis Design plans to add support for additional Andes RISC-V IP and processor configurations over time.
