Homework Help: Soft error pulse width in CPU

  1. Jul 19, 2012 #1
    1. The problem statement, all variables and given/known data
    Hi, I am trying to inject some faults into a CPU manually. But I am not sure what should the soft error (SET) pulse width should be? I know that is different in different case. Therefore, I am going to set up a random generator to generator the SET pulse width. But what range should I set?
    I have google the pulse width but it desnot give me any useful information for the range. Most of them are the SET pulse width for inverter.

    Best regard

    What computer are you using? Why are you doing this? What if your "soft error" crashes the PC for good?

    Thanks for your reply
    I am using a simply processor and run it in modelsim using verilog. I want to find out the soft error rate and do the recovery. Before the recovery stage, I need to see which block in the processor cause the most errors rate and then consider how much recovery blocks should I put in. I know ALU and control block normally cause the most fault in CPU but I would like to make the "balance" between each block for recovery.
