Hi everyone,

I am trying to run monte carlo to test the variation of the reading time of a 1T1C DRAM cell, where the bitline cap increases by delta V. I ran a transient analysis then used the function "cross" from the calculator so that I can send a scalar expression to the Monte Carlo, the full expression is : cross(v("/net04" ?result "tran") 0.555 1 "rising" nil nil)

However, still getting this error message which states that there is no statistical data generated for the test so the Monte Carlo run stopped, any ideas what could be the problem please?

    First of all, are you including models which have a statistics block in the model files to define the variation of various statistical parameters? That's a prerequisite for Monte Carlo.

    Secondly, which IC subversion are you using (Help->About will tell  you this) and simulator (presumably spectre?) subversion (this will be at the top of the spectre log file)?

    Regards,

    Andrew.
