Summary We download Pspice from TI website and

Summary • We download Pspice from TI website and run with Simplorer (ANSYS) however the result is not good. • We compare with TINA-TI. TINA should be functioned but Simplorer not. • We contact with ANSYS to verify the root cause. As of today ongoing action. • Request is to have unencrypted Pspice model to verify Toshiba internal. © 2018 Toshiba Corporation 1
