Accessing parameters in an SOA (asserts) file from the Virtuoso environment

FormerMember

Hello,

I am using Safe-Operating-Area or in Cadence language "assert checks" files in an analog Virtuoso flow. I'd like to be able to program the "duration" parameter in my SOA file from within the Virtuoso envionment. I'm not sure if this is possible and haven't found any threads that really help me up to now.

The files are just included in the "setup->model libraries" section of the ADE environment and contain variables definitions like

"parameters duration=10ns"

If anyone has any pointers to get me started I'd appreciate it.

Many thanks,

Matthew Cordrey-Gale

    Hi Matthew,

     If I understand your request correctly you want to control the parameter 'duration' of the assert statement within ADE environment. If so, you can add a design variable e.g myduration=10n in ADE. Also, in the assert statement you need to set duration param to myduration as shown below:

    e.g

    vgs_g45n1svt_LEV2 assert sub=g45n1svt primitive=bsim4 param=vgs min=-1.05 max=1.05 duration=myduration message="[EV]g45n1svt:VGS exceeds LEV2" level=warning

    Then you can control the duration param value by modifying myduration variable in ADE.

    Regards,
