Latest Patents

**Method of Forming Tree Structure Type Circuit, and Computer Product.** This method divides an LSI region into smaller regions and places circuit elements within them. It then forms a tree structure, performs schematic routing, and improves timing while accounting for clock skew. These steps are repeated a preset number of times before detailed placement and automatic routing are carried out.

**Activation Path Simulation Equipment and Activation Path Simulation Method.** This invention divides a transistor circuit into blocks based on the transistors’ pn-junction nodes. It determines activation patterns for each block using transistor characteristics, reducing unnecessary patterns and the number of simulations required. This approach can increase simulation speed.

Career Highlights

Konno’s described inventions address two stages of circuit development: organizing and routing LSI components, and efficiently simulating transistor circuits. Both focus on reducing design or computational effort while supporting circuit performance and analysis.

Collaborations

Konno’s listed coworkers include Terunobu Maruyama and Hiroshi Ikeda. The available information identifies Fujitsu Corporation as his company but does not specify the coworkers’ roles in the cited patents.

Conclusion

Tadashi Konno’s patent work reflects a focus on practical improvements to LSI design and transistor-circuit simulation, with an emphasis on efficient processes and reduced computational demands.
