    How to specify the parameters of build-in aging model of MOSRA in Hspice?

    Dear all, When I use MOSRA in HSPICE to simulate NBTI effect of using circuit by ten years, I am not sure how to specify the proper value of parameters under different technology nodes (e.g., 65nm, 32nm). For example, the parameter tito, which is the "first parameter for interface trap...

    Do the chips reserve the pins that can access its scan chain (if have)

    Hi all, Sorry to bother you. Do the manufactured chips (such as the micro-processor) on the market reserve the pins that can access their scan chains (e.g. input the data into the scan chain or shift out the responses), if such chips adopt scan-chain technique for DFT? Thanks very much for...

    some problem about the DLX instruction set and the corresponding architecture

    Hello, when I learning the DLX instruction set and its corresponding architecture, there are a mux in ID stage to select the one from three candidate numbers to calculate the new address. Two of them are immediate numbers, to which I find the corresponding instruction. However, the last...
