Defining Procedures from within a Pcell

ahamlett

With this code inside a pcell and myFunction used from within that pcell, no errors arise so is this a good practice?

I'm wondering if this might cause some errors down the line when a tool is reading the cadence database.

if(!procedurep(getd(stringToSymbol("myFunction"))) then
    procedure( myFunction(name)
        println(name stdout)
    )
)

  •  I am going to HAVE to agree with Lawrence and Andrew, defining procedures within a pcell is not a good idea. I would define them either before the pcDefinePcell or in a separate file and use libInit.il to load that procedure. Your implementation is very hard to debug.

    Inside a pcell, println causes an error. poport, the output port for println, is not available in the pcell interpreter. stdout and stderr are available so you should use fprintf:

    fprintf( stdout "%s => %L\n" pcCellView~>cellName outputValue )
