move instances of a pcell in the whole design

nuSkill

 

Hi, I have an existing layout and I changed the pcell type of the resistors used, the problem is the pcell origin of the original is different from the new one. I can replace them just fine, but all instances are shifted once I update it. Is there a way in skill to move all instances of the new pcells on my entire layout library? Perhaps a shift commnad or something? Below is a clip of how I replace the pcell. 

 if( inst~>cellName == "res_old" then

    leReplaceAnyInstMaster( inst "new_library" "res_new" nil )

    ;; shift the instance position code here???

)

 Appreciate any help.

    Hi Andrew, Thank you very much for your suggestions and sorry for the delayed reply. I actually kinda found some solution for my problem whis is by manipulating the inst~>xy property of the instance. I just need to figure out the math for the delta x and delta y transformation. It seems I must consider the inst~>orient property as well in order to achieve the original position of my instances after replacement. 

    Again thank you very much for your support.
