"Hidden" parameters in Pcell

RVERP

Hello,

 When I generate a Pcell using a function and it's arguments, my pcells do not generate correctly.

 I understand why, once the pcell is compiled, he has unknown variables, the one that where passed by the function.  IfI replace this variables with a parameter of the pcell, the functions arguments are stored and the pcell compiles.

I don't want to use variables for this to prevent having a long list.

Is there another way of doing this, some sort of hidden parameter or property?

 

So this doesn't work:

procedure( makeAcell(arg1 arg2)

pcDefinePcell(
 ...
 ...
w = arg1*arg2

))

 

This does work, but it's not what I want:

procedure( makeAcell(arg1 arg2)
 ...
;PCELL PARAMETERS
((Arg1 int arg1) (Arg2 int arg2))
 ...
))

  • Ok, thanks, this seems to work, with one exception.  If I use backquotes in a for loop, this doesn't seem to work.

     example:

     procedure(makeACell(arg1 arg2)
    eval(`pcDefinePCell(
      ...
      ...
      w=,arg1*,arg2
    for( n 1 ,arg1
    do something
    ) ;for
    ) ;pcDefinePCell
    ) ; eval
    ) ; procedure

    It looks like that he still needs the arg1 in the for loop.
