How to enter a variable into a symbol

AdamDaniels

 Hi,

Am trying to find out, whether it is possible to assign a global variable, which, for instance, is defined in the .cdsinit, to a label on a schematic or a symbol?

Thanks

Adam

    Hi Adam,

    If I've understood you correctly, then the way to do this is to create a label on a symbol (the symbol itself, not an instance), and make the text of the label "myGlobalVarName" and set the label type to be "ILLabel".

    Then when you instantiate the symbol, that label will be an evaluated SKILL expression, and should show the value of the variable.

    Regards,

    Andrew.

    I assumed that as well, but it didn't work, it just prints the variable name... however, have since figured out the solution.

    I saw another post and was able to extrapolate the answer. What I need to write in the ILLabel field is {myGlobalVarName}. Not knowing anything about Skill I assume the {} are used to extract the value from a variable, a bit like $ in UNIX.

    Thanks for the reply,

    Adam

    Hi Adam,

    Actually in SKILL a variable value is simply accessed by referring to it, no $ etc. is required.  The {} syntax is an alternative to using progn() around one or more statements as a grouping mechanism - the last statement in the block determines the return value of the block (hence the 'n' in the name progn to return the value of the nth statement, there is also a prog1 which returns the value of the first statement and also executes the rest of the statements in the block).  In this case {myGlobalVarName} and myGlobalVarName should behave in exactly the same way and return the value of the named variable.

    Anyway, I'm glad you got it working however you achieved it!

    Regards,

    Lawrence.
