RTL Design

Open-Silicon’s system engineers will construct a processor subsystem to meet the needs of the SoC application. This may be based upon an Open-Silicon reference design, or a fully custom implementation may be best suited to meet the coherence, latency and bandwidth requirements for the SoC.

Open-Silicon can also leverage ARM’s tooling (AMBA Designer) and methodology which specifically targets the quick stitching together of the SoC top-level using IP-XACT descriptions of the IP and a specification of the bus infrastructure.

  • Hardware includes Synopsys HAPS and others

Virtual Prototyping

  • Architectural exploration
  • Performance modeling
  • RTL Verification
  • Platform for early firmware & software development

Processor Optimization Hardening

SoC designers need hardened CPU processors that are optimized for performance and/or power. In today’s IC design, these processors will need to target a specific foundry technology, and sometimes metal stack. They will also need right-sized caches. Finally, the device application will drive whether a purely performance hardening is in order, or a more balanced performance/power tradeoff would yield a better market solution.

Open-Silicon offers processor hardening both as a service and as part of a complete SoC development solution. In addition to proven methodology capability at today’s leading edge process nodes, Open-Silicon brings the experience from over a hundred processor hardenings. In addition, Open-Silicon’s proprietary and patented technologies offer design-specific library augmentation flow for performance and/or power optimization. By adding 100-300 new cells to the standard cell library in a couple of Vts, the performance of these processors can be improved on average by 6-10%. With some of the industry’s broadest processor hardening experience, Open-Silicon is one of the leaders in processor implementation for embedded SoC designs.

Embedded Software

As a complete embedded CPU solutions provider, Open-Silicon offers processor software development. Customers who need to have low-level drivers, or middleware, written to complete a CPU-based embedded solution can use Open-Silicon for their product development needs. Open-Silicon has an experienced software team with capability in multiple operating systems (including Android and Linux) and with a wealth of applications. As part of this experience, the team is well versed in various memory optimization, performance and power optimization, and debug techniques.

In addition to the software capabilities, the team also offers  emulation solutions as part of an embedded SoC development effort. The emulation solutions are FPGA-based and well suited to complex SoC development design verification activities. Open-Silicon offers both the emulation system with reference design, and a complete design verification solution, as potential models to help customers quickly get their products to market.
