How to use procedure inside pcDefinePCell??

Hi Carlton,

Yes, you can do this. For example, here's an excerpt from a pcell definition done this way:

/*************************************************************************

*     By default the pcell will be placed in devlib library.             *
*     If an other library is needed you only have to pass the new        *
*     library name as parameter (it is optional).                        *
*     all pcell parameter are set to their default value.                *
*     this code call the main function AGDEfingerCap which draw the      *

Hai ,

    Thanks for the help.

I also want to know if i could write codes in two separate files and then link them.I meant if i create a code

 example: procedure( myProc(....... ) and save as myProc.il and based on the conditions in myProc.il can i create pcells in another code? Example: i make pcells using pcDefinePCell( ......) and save in myPcell.il.

Is it possible to link myProc.il and myPcell.il such that pcell in myPcell.il is created based on conditions in myProc.il? If its possible how to run these in separate files and link,if this is not pssible,please ignore my post.

Thanks,

Hi Carlton,

You can put whatever functions in whatever files you like. SKILL doesn't care - you need to load the files to use them though (e.g. using the load() function). Note it is possible to set up an autoload property so the source for a function is auto-loaded the first time you want to use it (search for autoload in the SKILL documentation). You don't need to "link" (whatever that means) the two files.

So you can define a function in myProc.il and refer to it in myPcell.il - provided that the code has been loaded. One point I should make is that if you have your pcell code (within the pcDefinePCell macro) call auxilliary functions, those need to be defined (i.e. loaded) whenever the pcell is used. In the example I posted, I call a function AGDEfingerCap which was defined in a separate file; I just needed to ensure that all those auxilliary functions were loaded from the pcell library's libInit.il file (note you don't need to call the pcDefinePCell from the libInit.il file though, as the code for the pcell is stored within the pcell cellView once it has been created).

Regards,

Andrew.
