pCell skill for beginners

Hi,

i'd like some advice for creating my first simple pCell from skill. I have no skill experience so i'm looking for a good place to start.

My ultimate aim (for now) is to create a rectangular via array with X and Y stretch handles. For example you have M1->M4(the top & bottom layers would be parameters) that you can stretch in X or Y and it fills with the max vias allowed by spacing rules. However to begin with i'd be happy to create a parameterised rectangle of M1 that i can stretch in one direction & take it from there.

Pointers to on-line tutorials and very simple examples would be great, right now i am blindly searching around source-link.

Thanks

Stu

I tried to load the skill code using
load("/home/fg3z7q/Desktop/jfet_fno_SKILL.il")
function jfet_fno_SKILL redefined
t
and when i call the function
jfet_fno_SKILL "fno_ts018_etest" "jfet_fno_SKILL"
it gives a waring stating that
*WARNING* Invalid libId - dd:0x19a9bad4
*WARNING* Invalid view name - nil
nil
Here I created a library named fno_ts018_etest and cell view named jfet_fno_SKILL before loading the skill.
Im a beginer and I appreciate any sort of help regarding this
Thanks,
Satish

I tried to load the skill code using
load("/home/fg3z7q/Desktop/jfet_fno_SKILL.il")
function jfet_fno_SKILL redefined
t
and when i call the function
jfet_fno_SKILL "fno_ts018_etest" "jfet_fno_SKILL"
it gives a waring stating that
*WARNING* Invalid libId - dd:0x19a9bad4
*WARNING* Invalid view name - nil
nil
Here I created a library named fno_ts018_etest and cell view named jfet_fno_SKILL before loading the skill.
Im a beginer and I appreciate any sort of help regarding this
Thanks,
Satish
