How to generate cells (layout view) from a txt file or csv file using pcell and skill code?

for reading a text or csv file you can do something like:
fp = infile("name_of_csv_file")
while( gets(line, fp)
;; get rid of terminating new line (if needed)
line = substring( line, 1, strlen(line)-1)
;; break into a list with an element for each entry
data = parseString(line, ",")

;; now do stuff with data
)

For adding instances to a layout the basic way is:

;; open the layout you want to write to
;; "a" == append to cell
;; "w" == overwrite cell
cv = dbOpenCellViewByType("mylib" "mycell" "layout" nil "a")

;; open (for reading) the cell you want to instantiate
master_id = dbOpenCellViewByType("pdklib" "nmos" "layout" nil "r")
refdes="I3" ;; some refdes (if you want to control it)
xy=12.3:45.6 ;; x-y location
orient = "R0" ;; other choices are "R90", "MY", etc.
new_inst = dbCreateInstance(cv, master_id, refdes, xy, orient, 1, t)

now you can update parameters on the newly created instance whose ID is in new_inst, for example:

new_inst->w = 6.8
new_inst->l = 0.8

Read the manual part about the functions here and that should at least get you in the right area of the docs to get going.
