How to generate warning messages for transient analysis?

AnnaS

Hi All, 

It's will be great if someone can help me to generate warning messages in transient analysis for transistor devices when a voltage reaches above a certain threshold on the gate. I don't know how can I generate these massages neither from gui nor from ocean script.

Thanks in advance.

Regards,

Anna

    Hi Marc,

    I generated warning messages. It works when I use level=error in netlist - however it does not work at all if level=warning. Could it be ICFB issue ?

    I use version: 5.10.41_USR5.90.69 .

    Here is an example:

    1. Warning message

    ****************************************************************************************

    //Device Checks created using ADE Device Checking Interface
    check1 assert dev=PM0 param=vth min=-0.5 max=-0.459 duration=1u \
        message="warning" level=warning

    //End Device Checks
    tranCheckLimit checklimit checkallasserts=yes enable=[ "check1" ] start=0u \
        stop=25u severity=warning
    tran tran stop=30u write="spectre.ic" writefinal="spectre.fc" \
        annotate=status maxiters=5

    *******************************************************************************************

     spectre completes with 0 errors, 0 warnings, and 0 notices

    2. Error messages

     

    ************************************************************************************

    //Device Checks created using ADE Device Checking Interface
    check1 assert dev=PM0 param=vth min=-0.5 max=-0.459 duration=1u \
        message="error" level=error

    //End Device Checks
    tranCheckLimit checklimit checkallasserts=yes start=0u stop=25u \
        severity=error
    tran tran stop=30u write="spectre.ic" writefinal="spectre.fc" \
        annotate=status maxiters=5

    ******************************************************************************************

    Error found by spectre at time = 1.53 us during transient analysis `tran'.
        ERROR (SPECTRE-4011): check1: error. Instance PM0, Parameter `vth' having value -842.113 mV has exceeded its lower bound `-500e-03'.

     Thanks,

      Anna
