Verification
Arasan’s SPMI Host and Device IP has been rigorously verified and has been made production ready. It has been verified through extensive simulation and compliance check using multiple 3rd party Verification IPs. The Coverage report is available upon request. The IPs are verified during Synthesis, place and route and are ready. This design can be ported to an ASIC or an FPGA design.
Support
The design core is delivered within 90 days from purchase. Thirty days of phone and email technical support is included. Optional maintenance support options are available for purchase.
