- Our company started originally as an ASIC company – but the first challenge we saw was how to connect IP from so many different sources with differing bus interfaces etc. As we worked to solve this problem, we say the opportunity to be an IP company with solutions for these and other SoC design challenges. We are the only IP provider with a full range of on-chip communications network IP that addresses the complete range of SoC markets. We do this with a standard GUI (Graphical User Interface) that enables architect’s to define the system, obtaining both SystemC and RTL that is right be design. The resultant IP block is one of the most configurable IP products offered by any company, yet right be design. Over 100 of the most demanding design have been done by about 2 dozen of the most demanding customers in the world. This includes 6 of the top 10 semiconductor companies. And the complete solution means our customers have an infrastructure to take care of the requirements today and tomorrow with our ongoing R&D efforts sustained by our onging business. We are recognized as the #1 IP company providing interconnect IP for the on-chip communications network used to connect IP blocks on an SoC.
