NetSpeed Systems (<a href=") | Full-time | ONSITE | San Jose, CA
We build software that designs and simulates Network on Chip interconnects along with the hardware to implement that interconnect in our customers' chips.  We need more software people to write C++ code that generates the Verilog implementation of the interconnect and to improve the built-in performance models of our components.
See <a href=" for some more specifics, although we're interested in more variety than just what that page indicates.
