Hierarchy editor - Implication of "stop point" on netlist

tito80

Hi, I am using Virtuoso hierarchy editor (config view) in IC6.1.5. As per the documentation, I am setting stop point on a particular instance so that the netlister does not desced further into that instance's schematic hierarchically. But I am seeing no change in the netlist produced with that config. For e.g., it was earlier:

subckt subckt_A

...

ends sunckt_A 

I1 (n1 n2) subckt_A

And after putting stop point on I1, it is still the same. So what does the "stop point" actually do?

  • That shouldn't happen. Are you definitely running ADE with the config view? Look in the banner of the ADE window and make sure it says that the view name is the config. If you create a config but simulate with the schematic, it won't use anything from the config.

    I just tried this (adding a stop point), and the underlying subckt did not get netlisted.

    However, since you said that you put the stop point on a particular instance (I first tried it on a particular cell), then you need to make sure you've got all instances of the subckt in question marked as stop points. Otherwise it will continue to expand the hierarchy for one of them and netlist the subckt definition.
