Physware, a company created by University of Washington electrical engineering professor Vikram Jandhyala, has raised $6.9 million in funding, according to a filing with the SEC. The company maintains operations in Bellevue and Silicon Valley, with CEO Raul Camposano serving out of the company’s Mountain View, California location.

Physware chief marketing officer Bala Vishwanath declined to comment on the filing, saying the company is in “semi-stealth mode.” Madrona’s Greg Gottesman, an early backer of Physware, also declined to comment.

Physware raised $2.5 million in 2008 from Madrona and WRF Capital, but it has flown under the radar as it serves its semiconductor customers.

Jandhyala is the Director of the Applied Computational Engineering lab and an Entrepreneurial Faculty Fellow at UW’s Center for Commercialization.

Physware sells its technology to the microelectronics industry, developing “high-capacity 3D electromagnetic signal integrity, power integrity and EMI analysis field solutions.” Customers include makers of microprocessors, memory, wireless RF systems such as Texas Instruments, Toshiba, Panasonic and Tabula, the latter of which just announced a $108 million funding round today.
