trig and targ timing in measure report while using spectre and simulation trace report

SatendraMaurya

Hi,

I was wondering if there is a way to report the time of actual measurement when trig and targ happened. I currently get the measures but have to trace back what time the trig/targ might have occured.

Also wondering if there is a way to get the percentage simulation time trace like 10% done 20% like that. My simulations run for couple of days and sometime it runs out of memory or lsf-wall clock time out. But then I have to load the waveform to get the info how far it went before the simulation died.

Also if there is a way to get the measures reported for however far the simulation was able to run.

    Hi Satendra,

    It might help to know how you're making these measurements? What are the measurement statements? Are you putting .measure statements in the netlist, or are you using SpectreMDL? Or something else? Then I might be able to give you some more directed suggestions...

    Regards,

    Andrew.

    Hi Andrew,

    Sorry this got missed between other comments. This is how the measurement statements are in my simulations:

    .meas tran sa_bnk_0_entry_0 trig v2(I0.XXIRAM_CNTLX4/XI12/MMNA1) val='pvdd/2' rise=1 td='11.150*period-(ftrans_data/2)' targ v2(I0.XILDIO<0>/XISENSE/XISAMP_BASE/MM6) val='pvdd*30/100' rise=1 td='11.150*period-(ftrans_data/2)'

    The result I am getting is like:

    sa_bnk_0_entry_0 = 1.56092e-10

    I would be expecting the report to be like

    sa_bnk_0_entry_0 = 1.56092e-10  trig @2.4ns targ@3.1ns

    Hi Andrew, 

    Any update on this.

    Also is there a way to only save measurments nodes in the waveform file. I donot want to save anything else.
