The ZSPNano is supported by VeriSilicon's powerful, easy to use ZView IDE based on industry standard Eclipse and GNU tools. ZView also includes a fast cycle accurate simulator and profiling and data graphing tools that help reduce time to market.

VeriSilicon also offers ZSP test chips and evaluation boards. ZSP cores are also supported by third party vendors providing RTOS and ESL tools.

A wide portfolio of optimized, field-proven software is readily available for the ZSPNano. Software deliverables are complete with API specification and example usage, allowing developers to focus their resources on system level integration. Software includes various DSP libraries, voice codecs, audio codecs, voice and audio pre-processing and post-processing functions and application framework.

The ZSPNano core is available for licensing. Deliverables include a fully synthesizable design, ZView tools and relevant application software.

VeriSilicon has offices worldwide with very experienced support engineers to help with any issue related to ZSP hardware or software deliverables.

VeriSilicon also offers hardware and software design services as part of its Design/Turnkey services.
