Schematic entry parameter as a function of instance name

yoyega

 Hi, I have a question concerning a schematic entry. Let's assume that I have defined a subcircuit that has pwl souce inside. This pwl source reads the point/time values from a file, and I want that the name of the file in the definition of the pwl source to be automatically set as a funcion of the name of the instance of the subcircuit. Does anyone knows how to do this?

Example:

subckt myckt
    I0 ( node1 node2 ) isource type=pwl file="a_function_of_the_name_of_the_instance_of_myckt"
    ...
end myckt

This way, if I have to instantiate several instances of myckt, each instance would automatically read point/time values from different files.

Thanks,
Pedro

  •  Hi, thank you for your replies. You are right Andrew, as I am using spectre oldmouldy's approach is not very straightforward. The point is that I have to instantiate and interconect 1024 instances of the same subcircuit (a pixel), and that each instance needs to be excited with a different independent current source, and that each current source has a different dc value. I don't want to entry all the 1024 schematic instances by hand. Do you think that skill language can be helpfull for this?...the truth is that I know nothing about skill programming...

     

    Thanks and regards,
