Integration of bsource in schematic views

MicheleA

Hi All,

while looking into some models of my design kit I stumbled upon this "bsource" component.

I then tried to instantiate one in a schematic, without success : I could not find any primitive with this name.

I reverted to the help to find out what a behavioural source is toghether with its many benefits when it comes to modeling.

My question : how can I create a component to be used in the schematic views, whose circuit is a bsource?

On a more general note, how can I "attach" a spectre netlist to a component, with symbol and properties?

Thanks for your help,

 Michele

  • Hi Michele,

    I've got a potential solution to the issue you're describing here.

    I created a component in my library called 'BSource' with a symbol and spectre view only (just copy a vsource symbol).

    Then, I edited the CDF to have the following:

    Component Parameter:
    Name: v
    Prompt: v
    Type: String
    Parse as CEL: Yes
    Parse as Number: No

    Simulation Information: spectre
    instParameters: v
    termOrder: PLUS MINUS
    componentName: bsource

     With this, I was able to instantiate a BSource subcircuit with the following parameter:
    v=sin(2*3.14159*(Fstart*$time+Fgain*$time*$time)) 

    I then could start up ADE, have it pull the parameters Fstart and Fgain from the BSource instance and simulate a transient chip simulation.
