Sonics is the leader in providing solutions that dramatically improve chip development economics as a result of outsourcing the interconnect design.

Sonics solutions have been used in over 100 million devices, including consumer appliances such as HDTVs; home routers; leading-edge cell phones; automotive camera-based applications; and as part of gaming platforms.
