    lvsIgnore, netlistIgnore Reply

    Hello colleagues,

    I have a question related to IC5.1.41: 
    In a schematic, it is possible to place the property "lvsIgnore" on a component, to exclude his component from LVS.  In other words, this component is taken into acount during netlisting and simulation, but not during LVS.
    my question is now:  Does there exisit a similar property to exclude a component from netlisting, but include it in LVS?  I would think of a property like "netlistIgnore" or "simIgnore".'


    Thanks in advance for helping me out,

    Hi Frank,

    You are close with your guess, "netlistIgnore" is very close to "nlIgnore"; there are two properties that can be used to control netlisting this way:

    nlAction = "ignore"
    nlIgnore = "vhdl"

    The nlAction string property can be set to "ignore" or "stop", the nlIgnore property can have one or more space separated netlisters that will ignore the component.  Please look for these in the documentation (CDSDoc / cdnshelp / Cadence Online Support) to get more detail on the usage.

    Hope this helps!
