    the warning when export stream in CADENCE

    Hi everyone, I meet a problem when I translate the layout to the gds file in CADENCE. first I translate the layout to the gds file, then for verifying the gds file, I translate the gds file to the layout form again. but the layout is different from original layout. so check the warning when...

    Silvaco ATLAS Loop issue

    Hi Korla, The version of ATLAS, which I use, have not the function of LOOP. But I think you can break up the loop and use two times sequentially executing program to replace it.

    can X-RAY lead to the Single Event Upset in circuit ?

    Thank you dick_freebird, In the book " Ionizing Radiation Effects in MOS Eevices and Circuits" it's mentioned a effect named DOSE-RATE UPSET,which is commonly used to refer to the loss of logic state information initiated by a high-amplitude, short-term pulse of ionizing radiation, most...

    can X-RAY lead to the Single Event Upset in circuit ?

    Hi everyone, I am recently studying the radiation effect on the circuit. I know the high-energy particle, like neutron or proton, can lead to the Single Event Upset in circuit. the X-RAY, a type of electromagnetic wave with very high energy, may have the obvious the characteristic of...

    the unit of capacitance in SILVACO TCAD ?

    Hello everyone, I used the silvaco TCAD to extract capacitance of the PN junction. first, using the 2D structure, the extracted capacitance with unit F/μm. then, I change to 3D structure, but the result also shows that the unit of capacitance with F/μm. I want to know why there is no...
